TIMEOUT
This field specifies a number of clock cycles (clk_slow). If an AHB-Lite bus transfer takes more than the specified number of cycles (timeout detection), the bus transfer is terminated with an AHB-Lite bus error and a fault is generated (and possibly recorded in the fault report structure(s)).
'0x0000'-'0xfffe': Number of clock cycles.
'0xffff': This value is the default/reset value and specifies that no timeout detection is performed: a bus transfer will never be terminated and a fault will never be generated.

GROUP_SEL
Specifies the trigger group:
'0'-'15': trigger multiplexer groups.
'16'-'31': trigger 1-to-1 groups.
[12:8]
read-write
TR_EDGE
Specifies if the activated trigger is treated as a level sensitive or edge sensitive trigger.
'0': level sensitive. The trigger reflects TR_CMD.ACTIVATE.
'1': edge sensitive trigger. The trigger is activated for two clk_peri cycles.
[29:29]
read-write
OUT_SEL
Specifies whether trigger activation is for a specific input or output trigger of the trigger multiplexer. Activation of a specific input trigger, will result in activation of all output triggers that have the specific input trigger selected through their TR_OUT_CTL.TR_SEL field. Activation of a specific output trigger, will result in activation of the specified TR_SEL output trigger only.
'0': TR_SEL selection and trigger activation is for an input trigger to the trigger multiplexer.
'1': TR_SEL selection and trigger activation is for an output trigger from the trigger multiplexer.
Note: this field is not used for trigger 1-to-1 groups.
[30:30]
read-write
ACTIVATE
SW sets this field to '1' to activate (set to '1') a trigger as identified by TR_SEL, TR_EDGE and OUT_SEL. HW sets this field to '0' for edge sensitive triggers AFTER the selected trigger is activated for two clk_peri cycles.
Note: when ACTIVATE is '1', SW should not modify the other register fields.
SW MUST NOT set ACTIVATE bit to '1' while updating the other register bits simultaneously. At first the SW MUST update the other register bits as needed, and then set ACTIVATE to '1' with a new register write.

DIV_SEL
(TYPE_SEL, DIV_SEL) specifies the divider on which the command (DISABLE/ENABLE) is performed.
If DIV_SEL is '255' and TYPE_SEL is '3' (default/reset value), no divider is specified and no clock signal(s) are generated.
[7:0]
read-write
TYPE_SEL
Specifies the divider type of the divider on which the command is performed:
0: 8.0 (integer) clock dividers.
1: 16.0 (integer) clock dividers.
2: 16.5 (fractional) clock dividers.
3: 24.5 (fractional) clock dividers.
[9:8]
read-write
PA_DIV_SEL
(PA_TYPE_SEL, PA_DIV_SEL) specifies the divider to which phase alignment is performed for the clock enable command. Any enabled divider can be used as reference. This allows all dividers to be aligned with each other, even when they are enabled at different times.
If PA_DIV_SEL is '255' and PA_TYPE_SEL is '3', 'clk_peri' is used as reference.
[23:16]
read-write
PA_TYPE_SEL
Specifies the divider type of the divider to which phase alignment is performed for the clock enable command:
0: 8.0 (integer) clock dividers.
1: 16.0 (integer) clock dividers.
2: 16.5 (fractional) clock dividers.
3: 24.5 (fractional) clock dividers.
[25:24]
read-write
DISABLE
Clock divider disable command (mutually exclusive with ENABLE). SW sets this field to '1' and HW sets this field to '0'.
The DIV_SEL and TYPE_SEL fields specify which divider is to be disabled.
The HW sets the DISABLE field to '0' immediately and the HW sets the DIV_XXX_CTL.EN field of the divider to '0' immediately.
[30:30]
read-write
ENABLE
Clock divider enable command (mutually exclusive with DISABLE). Typically, SW sets this field to '1' to enable a divider and HW sets this field to '0' to indicate that divider enabling has completed. When a divider is enabled, its integer and fractional (if present) counters are initialized to '0'. If a divider is to be re-enabled using different integer and fractional divider values, the SW should follow these steps:
0: Disable the divider using the DIV_CMD.DISABLE field.
1: Configure the divider's DIV_XXX_CTL register.
2: Enable the divider using the DIV_CMD_ENABLE field.
The DIV_SEL and TYPE_SEL fields specify which divider is to be enabled. The enabled divider may be phase aligned to either 'clk_peri' (typical usage) or to ANY enabled divider.
The PA_DIV_SEL and PA_TYPE_SEL fields specify the reference divider.
The HW sets the ENABLE field to '0' when the enabling is performed and the HW set the DIV_XXX_CTL.EN field of the divider to '1' when the enabling is performed. Note that enabling with phase alignment to a low frequency divider takes time. E.g. To align to a divider that generates a clock of 'clk_peri'/n (with n being the integer divider value INT_DIV+1), up to n cycles may be required to perform alignment. Phase alignment to 'clk_peri' takes affect immediately. SW can set this field to '0' during phase alignment to abort the enabling process.

DIV_SEL
Specifies one of the dividers of the divider type specified by TYPE_SEL.
If DIV_SEL is '255' and TYPE_SEL is '3' (default/reset value), no divider is specified and no clock control signal(s) are generated.
When transitioning a clock between two out-of-phase dividers, spurious clock control signals may be generated for one 'clk_peri' cycle during this transition. These clock control signals may cause a single clock period that is smaller than any of the two divider periods. To prevent these spurious clock signals, the clock multiplexer can be disconnected (DIV_SEL is '255' and TYPE_SEL is '3') for a transition time that is larger than the smaller of the two divider periods.

IOC_MASK
CPU floating point unit (FPU) exception mask for the CPU's FPCSR.IOC 'invalid operation' exception condition:
'0': The CPU's exception condition does NOT activate the CPU's floating point interrupt.
'1': the CPU's exception condition activates the CPU's floating point interrupt.
Note: the ARM architecture does NOT support FPU exceptions; i.e. there is no precise FPU exception handler. Instead, FPU conditions are captured in the CPU's FPCSR register and the conditions are provided as CPU interface signals. The interface signals are 'masked' with the fields a provide by this register (CM7_0_CTL). The 'masked' signals are reduced/OR-ed into a single CPU floating point interrupt signal. The associated CPU interrupt handler allows for imprecise handling of FPU exception conditions.
Note: the CPU's FPCSR exception conditions are 'sticky'. Typically, the CPU FPU interrupt handler will clear the exception condition(s) to '0'.
Note: by default, the FPU exception masks are '0'. Therefore, FPU exception conditions will NOT activate the CPU's floating point interrupt.

'0': The CPU's exception condition does NOT activate the CPU's floating point interrupt.
'1': the CPU's exception condition activates the CPU's floating point interrupt.
Note: the 'inexact' condition is set as a result of rounding. Rounding may occur frequently and is typically not an error condition. To prevent frequent CPU FPU interrupts as a result of rounding, this field is typically set to '0'.

IDC_MASK
CPU FPU exception mask for the CPU's FPCSR.IDC 'input denormalized' exception condition:
'0': The CPU's exception condition does NOT activate the CPU's floating point interrupt.
'1': the CPU's exception condition activates the CPU's floating point interrupt.
Note: if the CPU FPCSR.FZ field is set to '1', denormalized inputs are 'flushed to zero'. Dependent on the FPU algorithm, this may or may not occur frequently. To prevent frequent CPU FPU interrupts as a result of denormalized inputs, this field may be set to '0'.

ENABLED
Processor enable:
'0': Disabled. Processor clock is turned off and reset is activated. After SW clears this field to '0', HW automatically sets this field to '1'. This effectively results in a CM0+ reset, followed by a CM0+ warm boot.
'1': Enabled.
Note: The intent is that this bit is modified only through an external probe or by the CM4 while the CM0+ is in Sleep or DeepSleep power mode. If this field is cleared to '0' by the CM0+ itself, it should be done under controlled conditions (such that undesirable side effects can be prevented).
Note: The CM0+ CPU has a AIRCR.SYSRESETREQ register field that allows the CM0+ to reset the complete device (ENABLED only disables/enables the CM0+), resulting in a warm boot. This CPU register field has similar 'built-in protection' as this CM0_CTL register to prevent accidental system writes (the upper 16-bits of the register need to be written with a 0x05fa key value; see CPU user manual for more details).

IDX
The fault source index for which fault information is captured in DATA0 through DATA3. The fault information is fault source specific and described below.
Note: this register field (and associated fault source data in DATA0 through DATA3) should only be considered valid, when VALID is '1'.
[6:0]
read-write
VALID
Valid indication:
'0': Invalid.
'1': Valid. STATUS.IDX, DATA0, ..., DATA3 specify the fault.
Note: Typically, HW sets this field to '1' (on an activated HW fault source that is 'enabled' by the MASK registers) and SW clears this field to '0' (typically by boot code SW (after a warm system reset, when the fault is handled). In this typical use case scenario, the HW source fault data is simultaneously captured into DATA0, ..., DATA3 when the VALID field is set to '1'.
An exceptional SW use case scenario is identified as well. In this scenario, SW sets this field to '1' with a fault source index different to one of the defined HW fault sources. SW update is not restricted by the MASK registers). In both use case scenarios, the following holds:
- STATUS.IDX, DATA0, ..., DATA3 can only be written when STATUS.VALID is '0'; the fault structure is not in use yet. Writing STATUS.VALID to '1' effectively locks the fault structure (until SW clears STATUS.VALID to '0'). This restriction requires a SW update to sequentially update the DATA registers followed by an update of the STATUS register.
Note: For the exceptional SW use case, sequential updates to the DATA and STATUS registers may be 'interrupted' by a HW fault capture. In this case, the SW DATA register updates are overwritten by the HW update (and the STATUS.IDX field will reflect the HW capture)

Protection context mask for protection contexts '15' down to '1'. Bit PC_MASK_15_TO_1[i] indicates if the MPU MS_CTL.PC[3:0] protection context field can be set to the value 'i+1':
- PC_MASK_15_TO_1[i] is '0': MPU MS_CTL.PC[3:0] can NOT be set to 'i+1'; and PC[3:0] is not changed. If the protection context of the write transfer is '0', protection is not applied and PC[3:0] can be changed.
- PC_MASK_15_TO_1[i] is '1': MPU MS_CTL.PC[3:0] can be set to 'i+1'.
Note: When CPUSS_CM0_PC_CTL.VALID[i] is '1' (the associated protection context handler is valid), write transfers to PC_MASK_15_TO_1[i-1] always write '0', regardless of data written. This ensures that when valid protection context handlers are used to enter protection contexts 1, 2 or 3 through (HW modifies MPU MS_CTL.PC[3:0] on entry of the handler), it is NOT possible for SW to enter those protection contexts (SW modifies MPU MS_CTL.PC[3:0]).

SUBREGION_DISABLE
This field is used to individually disabled the eight equally sized subregions in which a region is partitioned. Subregion disable:
Bit 0: subregion 0 disable.
Bit 1: subregion 1 disable.
Bit 2: subregion 2 disable.
Bit 3: subregion 3 disable.
Bit 4: subregion 4 disable.
Bit 5: subregion 5 disable.
Bit 6: subregion 6 disable.
Bit 7: subregion 7 disable.
E.g., a 64 KByte address region (ATT0.REGION_SIZE is '15') has eight 8 KByte subregions. The access control as defined by ATT0 applies if the bus transfer address is within the address region AND the addressed subregion is NOT disabled. Note that the smallest region size is 256 B and the smallest subregion size is 32 B.

ADDR24
This field specifies the most significant bits of the 32-bit address of an address region. The region size is defined by ATT0.REGION_SIZE. A region of n Byte is always n Byte aligned.

E.g., a 64 KByte address region (REGION_SIZE is '15') is 64 KByte aligned, and ADDR24[7:0] are ignored.

The CM0+ MPU MS_CTL register is special: the PC field is modifiable by BOTH HW and SW (for all other masters, the MPU MS_CTL.PC field is modifiable by SW ONLY. For CM0+ PC field HW modifications, the following holds:
* On entry of a CM0_PC0/1/2/3_HANDLER exception/interrupt handler:
IF (the new PC is the same as MS_CTL.PC)
PC is not affected; PC_SAVED is not affected.
ELSE IF (CM0_PC_CTL.VALID[MS_CTL.PC])
An AHB-Lite bus error is generated for the exception handler fetch;
PC is not affected; PC_SAVED is not affected.
ELSE
PC = 'new PC'; PC_SAVED = PC (push operation).
* On entry of any other exception/interrupt handler:

2. Set the ECC_INJ_EN bit to '1'.
3. Confirm that the bit ECC_TEST_FAIL is '0'. If this is not the case, start over at item 1 because the eCT Flash was not idle.
4. Check the corrected data in FM_SRAM_ECC_CTL2.
5. Confirm that fault was reported to fault structure, and check syndrome (only applicable if
corrupted data was written in step 1).
6. If not finished, start over at 1 with different data.

Enable HVLVD1 voltage monitor. When the LVD is enabled, it takes 20us for it to settle. There is no hardware stabilization counter, and it may falsely trigger during settling. It is recommended that firmware keep the interrupt masked for at least 8us, write a 1'b1 to the corresponding SRSS_INTR field to any falsely pended interrupt, and then optionally unmask the interrupt. After enabling, it is further recommended to read the related PWR_LVD_STATUS field, since the interrupt only triggers on edges. This bit is cleared (LVD is disabled) when entering DEEPSLEEP to prevent false interrupts during wakeup.

FLL_ENABLE
Master enable for FLL. The FLL requires firmware sequencing when enabling, disabling, and entering/exiting DEEPSLEEP.
To enable the FLL, first enable the CCO by writing CLK_FLL_CONFIG4.CCO_ENABLE=1 and wait until CLK_FLL_STATUS.CCO_READY==1. Next, ensure the reference clock has stabilized and CLK_FLL_CONFIG3.BYPASS_SEL=FLL_REF. Next, write FLL_ENABLE=1 and wait until CLK_FLL_STATUS.LOCKED==1. Finally, write CLK_FLL_CONFIG3.BYPASS_SEL=FLL_OUT to switch to the FLL output. It takes seven reference clock cycles plus four FLL output cycles to switch to the FLL output. Do not disable the FLL before this time completes.
To disable the FLL, write CLK_FLL_CONFIG3.BYPASS_SEL=FLL_REF and (optionally) read the same register to ensure the write completes. Then, wait at least seven FLL reference clock cycles before disabling it with FLL_ENABLE=0. Lastly, disable the CCO by writing CLK_FLL_CONFIG4.CCO_ENABLE=0.
Before entering DEEPSLEEP, either disable the FLL using above sequence or use the following procedure to deselect/select it before/after DEEPSLEEP. Before entering DEEPSLEEP, write CLK_FLL_CONFIG3.BYPASS_SEL=FLL_REF to change the FLL to use its reference clock. After DEEPSLEEP wakeup, wait until CLK_FLL_STATUS.LOCKED==1 and then write CLK_FLL_CONFIG3.BYPASS_SEL=FLL_OUT to switch to the FLL output.

Trim for the Active-Regulator. This sets the output voltage level. This register is only reset by XRES/POR/BOD/HIBERNATE. The nominal output voltage is vccd=812.5mV + ACT_REG_TRIM*12.5mV. The actual output voltage will vary depending on conditions and load. The following settings are explicitly shown for convenience, and other values may be calculated using the formula:

ACT_REG_BOOST
Controls the tradeoff between output current and internal operating current for the Active Regulator. The maximum output current depends on the silicon implementation, but an application may limit its maximum current to less than that. This may allow a reduction in the internal operating current of the regulator. The regulator internal operating current depends on the boost setting:
2'b00: 50uA
2'b01: 100uA
2'b10: 150uA
2'b11: 200uA
The allowed setting is a lookup table based on the chip-specific maximum (set in factory) and an application-specific maximum (set by customer). The defaults are set assuming the application consumes the maximum allowed by the chip.
50mA chip: 2'b00 (default);
100mA chip: 2'b00 (default);
150mA chip: 50..100mA app => 2'b00, 150mA app => 2'b01 (default);

For this reason, if the WCO is intended as the clock source then choose it directly instead of routing through LFCLK.

Configures the WCO for different board-level connections to the WCO pins. For example, this can be used to connect an external watch crystal oscillator instead of a watch crystal. In all cases, the two related GPIO pins (WCO input and output pins) must be configured as analog connections using GPIO registers, and they must be hooked at the board level as described below. Configure this field before enabling the WCO, and do not change this setting when WCO_EN=1.
0: Watch crystal. Connect a 32.768 kHz watch crystal between WCO input and output pins.

When this bit is set the RTC registers will be copied to user registers and frozen so that a coherent RTC value can safely be read. The RTC will keep on running.
Do not set the read bit if the RTC is still busy with a previous update (see RTC_BUSY bit) or if the Write bit is set. Do not set the Read bit at the same time that the Write bit is cleared.

WRITE
Write bit
Only when this bit is set can the RTC registers be written to (otherwise writes are ignored). This bit cannot be set if the RTC is still busy with a previous update (see RTC_BUSY bit) or if the Read bit is set or getting set.
The user writes to the RTC user registers, when the Write bit is cleared by the user then the user registers content is copied to the actual RTC registers.
Only user RTC registers that were written to will get copied, others will not be affected.
When the SECONDS field is updated then TICKS will also be reset (WDT is not affected).
When the Write bit is cleared by a reset (brown out/DeepSleep) then the RTC update will be ignored/lost.
Do not set the Write bit if the RTC if the RTC is still busy with a previous update (see RTC_BUSY). Do not set the Write bit at the same time that the Read bit is cleared.

Calibration value for absolute frequency (at a fixed temperature). Each step causes 128 ticks to be added or removed each hour. Effectively that means that each step is 1.085ppm (= 128/(60*60*32,768)).
Positive values 0x01-0x3c (1..60) add pulses, negative values remove pulses, thus giving a range of +/-65.1 ppm (limited by 60 minutes per hour, not the range of this field)
Calibration is performed hourly, starting at 59 minutes and 59 seconds, and applied as 64 ticks every 30 seconds until there have been 2*CALIB_VAL adjustments.

WAIT_FOR_DEACT
Specifies whether the controller should wait for the input trigger to be deactivated; i.e. the selected system trigger is not active. This field is used to synchronize the controller with the agent that generated the trigger. This field is ONLY used at the completion of the transfer as specified by TR_IN. E.g., a TX FIFO indicates that it is empty and it needs a new data sample. The agent removes the trigger ONLY when the data sample has been written by the controller AND received by the agent. Furthermore, the agent's trigger may be delayed by a few cycles before it reaches the controller. This field is used for level sensitive trigger, which reflect state (pulse sensitive triggers should have this field set to '0'). The wait cycles incurred by this field reduce DW controller performance.
'0': Do not wait for trigger de-activation (for pulse sensitive triggers).

- If the descriptor type is 'memory copy', the interrupt is generated after the execution of a memory copy transfer.
- If the descriptor type is 'scatter' the interrupt is generated after the execution of a scatter transfer.
'2': An interrupt is generated after the execution of the current descriptor (independent of the value of DESCR_NEXT_PTR.ADDR of the current descriptor).
'3': An interrupt is generated after the execution of the current descriptor and the current descriptor's DESCR_NEXT_PTR.ADDR is '0'.

read-only
TR_OUT_TYPE
Specifies when an output trigger is generated:
'0': An output trigger is generated after a single transfer.
'1': An output trigger is generated after a single 1D transfer or a memory copy transfer.
- If the descriptor type is 'single', the output trigger is generated after a single transfer.
- If the descriptor type is '1D' or '2D', the output trigger is generated after the execution of a 1D transfer.
- If the descriptor type is 'memory copy', the output trigger is generated after the execution of a memory copy transfer.
- If the descriptor type is 'scatter', the output trigger is generated after the execution of a scatter transfer.
'2': An output trigger is generated after the execution of the current descriptor.
'3': An output trigger is generated after the execution of a descriptor list: after the execution of the current descriptor AND the current descriptor's DESCR_NEXT_PTR.ADDR is '0'.
[5:4]
read-only
TR_IN_TYPE
Specifies the input trigger type (not to be confused with the descriptor type):
'0': A trigger results in the execution of a single transfer. The descriptor type can be single, 1D or 2D.
'1': A trigger results in the execution of a single 1D transfer.
- If the descriptor type is 'single', the trigger results in the execution of a single transfer.
- If the descriptor type is '1D' or '2D', the trigger results in the execution of a 1D transfer.
- If the descriptor type is 'memory copy', the trigger results in the execution of a memory copy transfer.
- If the descriptor type is 'scatter', the trigger results in the execution of an scatter transfer.
'2': A trigger results in the execution of the current descriptor.
'3': A trigger results in the execution of the current descriptor and continues (without requiring another input trigger) with the execution of the next descriptor using the next descriptor's information.
[7:6]
read-only
DATA_PREFETCH
Source data prefetch:
'0': No source data prefetch. Source data transfers are only initiated AFTER the input trigger is activated.
'1': Source data prefetch. Source data transfers are initiated as soon as the channel is enabled, the current descriptor pointer is NOT '0' and there is space available in the channel's data FIFO. When the input trigger is activated, the trigger can initiate destination data transfers with data that is already in the channel's data FIFO. This effectively shortens the initial delay of the data transfer.
Note: data prefetch should be used with care, to ensure that data coherency is guaranteed and that prefetches do not cause undesired side effects.
[8:8]
read-only
DATA_SIZE
Specifies the data element size:
'0': Byte (8 bits).
'1': Halfword (16 bits).
'2': Word (32 bits).
DATA_SIZE, SRC_TRANSFER_SIZE and DST_TRANSFER_SIZE together determine how data elements are transferred. The following are the 9 legal settings:
- DATA is 8 bit, SRC is 8 bit, DST is 8 bit.
- DATA is 8 bit, SRC is 32 bit (higher 24 bits are dropped), DST is 8 bit.
- DATA is 8 bit, SRC is 8 bit, DST is 32 bit (higher 24 bits are made '0').
- DATA is 8 bit, SRC is 32 bit (higher 24 bits are dropped), DST is 32 bit (higher 24 bits are made '0').
- DATA is 16 bit, SRC is 16 bit, DST is 16 bit.
- DATA is 16 bit, SRC is 32 bit (higher 16 bits are dropped), DST is 16 bit.
- DATA is 16 bit, SRC is 16 bit, DST is 32 bit (higher 16 bits are made '0').
- DATA is 16 bit, SRC is 32 bit (higher 16 bits are dropped), DST is 32 bit (higher 16 bits are made '0').
- DATA is 32 bit, SRC is 32 bit, DST is 32 bit.
Note: this field is not used for a 'memory copy' descriptor type. Note: this field must be set to '2' for a 'initialization' descriptor type.
[17:16]

CH_DISABLE
Specifies whether the channel is disabled or not after completion of the current descriptor (independent of the value of the DESCR_NEXT_PTR value):
'0': Channel is not disabled.
'1': Channel is disabled.
[24:24]
read-only
SRC_TRANSFER_SIZE
Specifies the bus transfer size to the source location:
'0': As specified by DATA_SIZE.
'1': Word (32 bits).
Distinguishing bus transfer size from data element size allows for source components with data elements that are smaller than their 32-bit bus interface width. E.g., an ADC source has a 32-bit bus transfer size, but only provides a 16-bit data element.
Note: this field is not used for a 'memory copy' descriptor type. Note: this field must be set to '1' for a 'scatter' descriptor type.
[26:26]
read-only
DST_TRANSFER_SIZE
Specifies the bus transfer size to the destination location:
'0': As specified by DATA_SIZE.
'1': Word (32 bits).
Distinguishing bus transfer size from data element size allows for destination components with data elements that are smaller than their 32-bit bus interface width. E.g., a DAC destination has a 32-bit bus transfer size, but only requires a 16-bit data element.
Note: this field is not used for a 'memory copy' descriptor type. Note: this field must be set to '1' for a 'scatter' descriptor type.

'1': 1D transfer.
The DESCR_X_SIZE and DESCR_X_INCR registers are present, the DESCR_Y_SIZE and DESCR_Y_INCR are NOT present. A 1D transfer consists out of DESCR_X_SIZE.X_COUNT+1 single transfers. The DESCR_NEXT_PTR is at offset 0x14.
'2': 2D transfer.
The DESCR_X_SIZE, DESCR_X_INCR, DESCR_Y_SIZE and DESCR_Y_INCR registers are present. A 2D transfer consists of (DESCR_X_SIZE.X_COUNT+1)*(DESCR_Y_SIZE.Y_COUNT+1) single transfers. The DESCR_NEXT_PTR is at offset 0x1c.
'3': Memory copy.
The DESCR_X_SIZE register is present, the DESCR_X_INCR, DESCR_Y_SIZE and DESCR_Y_INCR are NOT present. A memory copy transfer copies DESCR_X_SIZE.X_COUNT+1 Bytes and may use Byte, halfword and word transfers. The DESCR_NEXT_PTR is at offset 0x10.
'4': Scatter transfer. The DESCR_X_SIZE register is present, the DESCR_DST, DESCR_X_INCR, DESCR_Y_SIZE and DESCR_Y_INCR are NOT present.
'5'-'7': Undefined.
After the execution of the current descriptor, the DESCR_NEXT_PTR address is copied to the channel's CH_CURR_PTR address and CH_STATUS.X_IDX and CH_STATUS.Y_IDX are set to '0'.

START
FW sets this field to '1' to start a program operation. HW sets this field to '0' to indicate that the operation has completed.
Note: it is good practice to verify the result of a program operation by reading back a programmed eFUSE memory location. Programming can only change an eFUSE memory bit from '0' to '1'; i.e. a programming operation is a 'one-off' operation for each eFUSE memory bit: once a bit is changed to '1', it can NEVER be changed back to '0' as a hardware fuse is blown.
Programming a memory bit to '1' requires blowing a fuse and requires an eFUSE macro operation. Therefore, this programmiong operation takes time (as specified by the SEQ_PROGRAM_CTL reguisters). Programming amemory bit to '0' does not require an eFUSE macro operation (it is the default eFUSE macro state). Therefore, this programming operation is almost instantaneous.
Note: during a program operation, a read operation can not be performed. An AHB-Lite read transfer to the eFUSE memory during a program operation results in an AHB-Lite bus error.

DRIVE_MODE0
The GPIO drive mode for IO pin 0. Resistive pull-up and pull-down is selected in the drive mode.
Note: when initializing IO's that are connected to a live bus (such as I2C), make sure the peripheral and HSIOM (HSIOM_PRT_SELx) is properly configured before turning the IO on here to avoid producing glitches on the bus.
Note: that peripherals other than GPIO & UDB/DSI directly control both the output and output-enable of the output buffer (peripherals can drive strong 0 or strong 1 in any mode except OFF='0').
Note: D_OUT, D_OUT_EN are pins of GPIO cell.

VDDIO_ACTIVE
Indicates presence or absence of VDDIO supplies (i.e. other than VDDD, VDDA) on the device (supplies are numbered 0..n-1). Note that VDDIO supplies have basic (crude) supply detectors only. If separate, robust, brown-out detection is desired on IO supplies, on-chip or off-chip analog resources need to provide it. For these bits to work reliable, the supply must be within valid spec range (per datasheet) or held at ground. Any in-between voltage has an undefined result.
'0': Supply is not present
'1': Supply is present
When multiple VDDIO supplies are present, they will be assigned in alphanumeric ascending order to these bits during implementation.
For example 'vddusb, vddio_0, vddio_a, vbackup, vddio_r, vddio_1' are present then they will be assigned to these bits as below:
0: vbackup,
1: vddio_0,

This selection is intended for synchronous operation on a PCLK specified clock frequency ('clock_smartio_pos_en'). Note that the fabric's clocked elements are frequency aligned, but NOT phase aligned to 'clk_sys'.
'17': clk_smartio/rst_sys_dpslp_n. Used for both DeepSleep functionality synchronous logic on 'clk_smartio' (note that 'clk_smartio' is NOT available in DeepSleep and Hibernate power modes). This selection is intended for synchronous operation on a PCLK specified clock frequency ('clock_smartio_pos_en'). Note that the fabric's clocked elements are frequency aligned, but NOT phase aligned to 'clk_sys'.
'18': Same as '17'. Note that the M0S8 SMARTIO version used the Hibernate reset for this value, but the MXS40 SMARTIO version does not support Hibernate functionality.
'19': clk_lf/rst_lf_dpslp_n (note that 'clk_lf' is available in DeepSleep power mode). This selection is intended for synchronous operation on'clk_lf'. Note that the fabric's clocked elements are frequency aligned, but NOT phase aligned to other 'clk_lf' clocked elements.
'20'-'30': Clock source is constant '0'. Any of these clock sources should be selected when the IP is disabled to ensure low power consumption.
'31': asynchronous mode/'1'. Select this when clockless operation is configured.
NOTE: Two positive edges of the selected clock are required for the block to be enabled (to deactivate reset). In asynchronous (clockless) mode clk_sys is used to enable the block, but is not available for clocking.

HLD_OVR
IO cell hold override functionality. In DeepSleep power mode, the HSIOM holds the IO cell output and output enable signals if Active functionality is connected to the IO pads. This is undesirable if the SMARTIO is supposed to deliver DeepSleep output functionality on these IO pads. This field is used to control the hold override functionality from the SMARTIO:
'0': The HSIOM controls the IO cell hold override functionality ('hsiom_hld_ovr').
'1': The SMARTIO controls the IO cel hold override functionality:
- In bypass mode (ENABLED is '0' or BYPASS[i] is '1'), the HSIOM control is used.
- In NON bypass mode (ENABLED is '1' and BYPASS[i] is '0'), the SMARTIO sets hold override to 'pwr_hld_ovr_hib' to enable SMARTIO functionality in DeepSleep power mode (but disables it in Hibernate or Stop power mode).

ENABLED
Enable for programmable IO. Should only be set to '1' when the programmable IO is completely configured:
'0': Disabled (signals are bypassed; behavior as if BYPASS is 0xFF). When disabled, the fabric (data unit and LUTs) reset is activated.
If the IP is disabled:
- The PIPELINE_EN register field should be set to '1', to ensure low power consumption by preventing combinatorial loops.
- The CLOCK_SRC register field should be set to '20'-'30' (clock is constant '0'), to ensure low power consumption.
'1': Enabled. Once enabled, it takes 3 'clk_fabric' clock cycles till the fabric reset is de-activated and the fabric becomes fully functional. This ensures that the IO pins' input synchronizer states are flushed when the fabric is fully functional.

SENSE_DIV
The length-1 of the Sense modulation 'clock' period in clk_csd cycles. For regular CSD one sense clock cycle = one conversion (=phi1+phi2) .
Note this is the base divider, clock dithering may change the actual period length.
Note that SENSE_DIV must be at least 1 and additionally also allow for one clk_hf of non overlap (if OVERLAP_HI1/2 is set) on both phases, i.e. if clk_csd=clk_hf then SENSE_DIV must be >=3.
In addition the FILTER_DELAY needs to be added to the minimum allowed SENSE_DIV value.
[11:0]
read-write
LFSR_SIZE
Selects the length of the LFSR which determines the LFSR repeat period. LFSR_BITS LSB of the LFSR are used for the clock dithering variation on the base period (was PRS in CSDv1). Whenever the LFSR is used (non zero value in this field) the LFSR_CLEAR bit should also be set.

LFSR_SCALE
Shift the LFSR output left by LSFR_SCALE bits before adding to SENSE_DIV. This dithering is disabled when SEL_LSFR_MSB is set.
The clock divider to be used = (SENSE_DIV+1) + (SEL_LSFR_MSB ? 0 : (LFSR_OUT<<LFSR_SCALE)).
Note that the clock divider including the dithering term must fit in 12 bits, otherwise the result is undefined.
[23:20]
read-write
LFSR_CLEAR
When set, forces the LFSR to it's initial state (all ones). This bit is automatically cleared by hardware after the LFSR is cleared, which is at the next clk_csd positive edge. This bit should be set whenever this register is written and the LFSR is used.
Note that the LFSR will also get reset to all ones during the AutoZero_1/2 states.
[24:24]
read-write
SEL_LFSR_MSB
Use the MSB of configured LSFR size as csd_sense signal. Intended to be used only with bit 8 or 12-bit LFSR size for CSDv1 backward compatibility (PRS). When this bit is set then clock divider dithering is disabled and SENSE_WIDTH is disabled.
[25:25]
read-write
LFSR_BITS
Selects the number of LSB bits to use from the LSFR to provide the clock dithering variation on the base period.
Caveat make sure that SENSE_DIV > the maximum absolute range (e.g. for 4B SENSE_DIV > 8), otherwise results are undefined.

Defines the length of the first phase of the sense clock in clk_csd cycles.
A value of 0 disables this feature and the duty cycle of csd_sense will be 50 percent, which is equal to SENSE_WIDTH = (SENSE_DIV+1)/2, or when clock dithering is used that becomes [(SENSE_DIV+1) + (LFSR_OUT << LSFR_SCALE)]/2. At all times it must be assured that the phases are at least 2 clk_csd cycles (1 for non overlap, if used), if this rule is violated the result is undefined.
Note that this feature is not available when SEL_LFSR_MSB (PRS) is selected.

OVERLAP_PHI1
NonOverlap or not for Phi1 (csd_sense=0).
0 = Non-overlap for Phi1, the Phi1 signal is csd_sense inverted except that the signal goes low 1 clk_sample before csd_sense goes high. Intended usage: new low EMI CSD/CSX with static GPIO.
1 = 'Overlap' (= not non-overlap) for Phi1, the Phi1 signal is csd_sense inverted. Intended usage: legacy CSD with GPIO switching, the GPIO internal circuit ensures that the switches are non-overlapping.

In those states leg3 is controlled by the ADC configuration and the HSCMP output. In addition this leg3 enable bit can optionally be mixed with DSI (see DSI_CTRL_EN).
When LEG3_EN=1 also the IDACB polarity is controlled by the ADC sequencer.

In PWM_PR mode PEROD_BUFF defines the LFSR polynomial. Each bit represents a tap of the shift register which can be feed back to the MSB via an XOR tree.
Examples for GRP_CNT_WIDTH = 16:
- Maximum length 16bit LFSR
- polynomial x^16 + x^14 + x^13 + x^11 + 1
- taps 0,2,3,5 -> PERIOD = 0x002d
- period is 2^16-1 = 65535 cycles
- Maximum length 8bit LFSR:
- polynomial x^8 + x^6 + x^5 + x^4 + 1
- taps 8,10,11,12 (realized in 8 MSBs of 16bit LFSR)
- period is 2^8-1 = 255 cycles
In SR mode PERIOD_BUFF defines which tap of the shift register generates the PWM output signals. For a delay of n cycles (from capture event to PWM output) the bit CNT_WIDTH-n should be set to '1'. For a shift register function only one tap should be use, i.e. a one-hot value must be written to PERIOD_BUFF. If multiple bits in PERIOD_BUFF are set then the taps are XOR combined.

The following procedure should be followed to disable the LS generator:
1. If LS_EN=0 we are done. Exit the procedure.
2. Check that LS_EN_STAT=1. If not, wait until it is. This will catch the case of a recent enable (LS_EN=1) that has not taken effect yet.

OUT_RCVD
When set this bit indicates a valid OUT packet has been received and ACKed. This bit is updated to '1' after the last received packet in an OUT transaction. When clear this bit indicates no OUT received. It is cleared by any writes to the register.
[5:5]
read-write
IN_RCVD
When set this bit indicates a valid IN packet has been received. This bit is updated to '1' after the host acknowledges an IN data packet. When clear this bit indicates either no IN has been received or that the host did not acknowledge the IN data by sending ACK handshake. It is cleared by any writes to the register.
[6:6]
read-write
SETUP_RCVD
When set this bit indicates a valid SETUP packet was received and ACKed. This bit is forced HIGH from the start of the data packet phase of the SETUP transaction until the start of the ACK packet returned by the SIE. The CPU is prevented from clearing this bit during this interval. After this interval the bit will remain set until cleared by firmware. While this bit is set to '1' the CPU cannot write to the EP0_DRx registers. This prevents firmware from overwriting an incoming SETUP transaction before firmware has a chance to read the SETUP data. This bit is cleared by any non-locked writes to the register.

Notes:
- This bit is set to the default value when the RST bit of the Host Control 1 Register (HOST_CTL1) is set to '1'.
- The PRE packet isn't supported.
- Do not set '100' to the TKNEN bit when the SOFBUSY bit of the Host Status Register (HOST_STATUS) is '1'
- Mode should be USB Host before writing data to this bit.
- When issuing a token again after the token interrupt flag (CMPIRQ) has been set to '1', wait for 3 cycles or more after a USB transfer clock (12 MHz in the full-speed mode, 1.5 MHz in the low-speed mode) was output, then write data to this bit.
- Read the value of TKNEN bit if a new value is written in it .Continue writing in this bit until a retrieved value equals a new value written in. During this checking process, it is needed to prevent any interrupt.
- Take the following steps when CMPIRQ bit of Interrupt USB Host Register (INTR_USBHOST) is set to '1' by finishing IN token or Isochronous IN token.
1. Read HS bit of Host Error Status Register (HOST_ERR), then set CMPIRQ bit to '0'.
2. Set EPn bit of Host DMA Enable Register (HOST_DMA_ENBL) (n=1 or 2) to '1' if HS bit of Host Error Status Register (HOST_ERR) is equal to '00' and wait until EPn bit of Host DMA Data Request Register (HOST_DMA_DREQ) changes to '1'. Finish the IN token processing if HS bit is not equal to '00'.

This bit sets a mode that uses DMA for writing or reading transfer data to/from send/receive buffer, and automatically transfers the send/receive data synchronized with an data request in the IN or OUT direction. Until the data size set in the DMA is reached, the data is transferred.
'0' : Releases the automatic buffer transfer mode.
'1' : Sets the automatic buffer transfer mode.
Note :
- The CPU must not access the send/receive buffer while the DMAE bit is set to '1'. For data transfer in the IN direction, set the DMA transfer size to the multiples of that set in PKS bits of the Host EP1 Control Register (HOST_EP1_CTL) and Host EP2 Control Register (HOST_EP2_CTR).
[11:11]

DIR
This bit specifies the transfer direction the Endpoint support.
'0' : IN Endpoint.
'1' : OUT Endpoint
Note:
- This bit must be changed when INI_ST bit of the Host Endpoint 2 Status Register (HOST_EP2_STATUS) is '1'.
[12:12]
read-write
BFINI
This bit initializes the send/receive buffer of transfer data. The BFINI bit is also automatically set by setting the RST bit of the HOST Control 1 Register (HOST_CTL1). If the RST bit was used for resetting, therefore, set the RST bit to '0' before clearing the BFINI bit.
'0' : Clears the initialization.
'1' : Initializes the send/receive buffer
Note :
- The EP2 buffer has a double-buffer configuration. The BFINI bit initialization initializes the double buffers concurrently and also initializes the EP2DRQ and EP2SPK bits.

SIZE2
These bits indicate the number of data bytes written to the receive buffer when IN packet transfer of EP2 has finished.
The indication range is from 0x000 to 0x40.
Note :
- These bits are set to the data size transferred in the IN direction and written to the buffer. Therefore, a value read during transfer in the OUT direction has no effect.

'1' : Initialized
Note:
- This bit isn't set to '0' or '1' immediately evne if BFINI bit of the Host Endpoint 2 Control Register (HOST_EP2_CTL) is set to '0' or '1'.

BLOCK
Specifies what happens for MMIO interface read accesses to an empty RX data FIFO or to a full TX format/data FIFO. Note: the FIFOs can only be accessed in MMIO_MODE.
This field is not used for test controller accesses.
[24:24]
read-write
BUS_ERROR
0': Generate an AHB-Lite bus error. This option is useful when SW decides to use polling on STATUS.TR_BUSY to determine if a interface transfer is no longer busy (transfer is completed). This option adds SW complexity, but limits the number of AHB-Lite wait states (and limits ISR latency).
0
WAIT_STATES
1': Introduce wait states. This setting potentially locks up the AHB-Lite infrastructure and may increase the CPU interrupt latency.This option is useful when SW performs TX/RX data FIFO accesses immediately after a command is setup using the TX format FIFO. This option has low SW complexity, but may result in a significant number of AHB-Lite wait states (and may increase ISR latency).

ENABLED
IP enable:
'0': Disabled. All non-retention registers are reset to their default value when the IP is disabled. When the IP is disabled, the XIP accesses produce AHB-Lite bus errors.
'1': Enabled.
Note: Before disabling the IP, SW should ensure that the IP is NOT busy (STATUS.BUSY is '0'), otherwise illegal interface transfers may occur.

When BUSY is '0', the IP can be safely disabled without:
- the potential loss of transient write data.
- the potential risk of aborting an inflight SPI device interface transfer.
When BUSY is '0', the mode of operation (XIP_MODE or MMIO_MODE) can be safely changed.

DATA20
Command data. The higher two bits DATA[19:18] specify the specific command
'0'/TX: A SPI transfer always start with a TX command FIFO entry of the 'TX' format.
- DATA[17:16] specifies the width of the data transfer:
- '0': 1 bit/cycle (single data transfer).
- '1': 2 bits/cycle (dual data transfer).
- '2': 4 bits/cycle (quad data transfer).
- '3': 8 bits/cycle (octal data transfer).
- DATA[15]: specifies whether this is the last TX Byte; i.e. whether the 'spi_select_out[3:0]' IO output signals are de-activated after the transfer.
- DATA[11:8] specifies which of the four devices are selected. DATA[11:8] are directly mapped to 'spi_select_out[3:0]'. Two devices can be selected at the same time in dual-quad mode.
- '0': device deselected
- '1': device selected
- DATA[7:0] specifies the transmitted Byte.
'1'/TX_COUNT: The 'TX_COUNT' command relies on the TX data FIFO to provide the transmitted bytes. The 'TX_COUNT' command is ALWAYS considered to be the last command of a SPI data transfers.
- DATA[17:16] specifies the width of the transfer.
- DATA[15:0] specifies the number of to be transmitted Bytes (minus 1) from the TX data FIFO.
'2'/RX_COUNT: The 'RX_COUNT' command relies on the RX data FIFO to accept the received bytes. The 'RX_COUNT' command is ALWAYS considered to be the last command of a SPI data transfers.
- DATA[17:16] specifies the width of the transfer.
- DATA[15:0] specifies the number of to be transmitted Bytes (minus 1) to the RX data FIFO.
'3'/DUMMY_COUNT: The 'DUMMY_COUNT' command conveys dummy cycles. Dummy cycles are used to implement a Turn-Around time in which the SPI master changes from a transmitter driving the data lines to a receiver receiving on the same data lines. The 'DUMMY_COUNT' command is ALWAYS considered to be NOT the last command of a SPI data transfers; i.e. it needs to be followed by another command.
- DATA[15:0] specifies the number of dummy cycles (minus 1). In dummy cycles, the data lines are not driven.

In dual quad SPI data transfer, the two devices should have the same ADDR and MASK register settings. The device control information (ADDR_CTL, RD_CMD_CTL, etc.) are provided by the MMIO control registers of the device with the lowest index.
The most significant bit fields are constants and set based on the SMIF_XIP_ADDR parameter. The most significant bits are identified on the SMIF_XIP_MASK parameter. E.g., if SMIF_XIP_MASK is 0xff00:0000 (16 MB XIP memory region), ADDR[31:24] = SMIF_XIP_ADDR[31:24].

The most significant bit fields are constants and set to'1'. The most significant bits are identified on the SMIF_XIP_MASK parameter. E.g., if SMIF_XIP_MASK is 0xff00:0000 (16 MB XIP memory region), MASK[31:24] = 0xff.

The lower significant address Bytes of the transfer request are used as XIP address to the external device. Note that for dual quad SPI data transfer, the transfer request address is divided by 2. Therefore, the transfer request address needs to be a multiple of 2. If the trasnfer requestaddress is NOT a multiple of 2, the XIP_ALIGNMENT_ERROR interrupt cause is activated.

DIV2
Specifies if the AHB-Lite bus transfer address is divided by 2 or not:
'0': No divide by 2.
'1': Divide by 2.
This functionality is used for read and write operation in XIP, dual quad SPI mode; i.e. this DIV2 must be set to '1' in dual quad SPI mode. If the transfer request address is NOT a multiple of 2 or the requested number of Bytes is not a multiple of 2, the XIP_ALIGNMENT_ERROR interrupt cause is activated.

0= No Error: No error occurred since LEC has been reset by successful reception or transmission.
1= Stuff Error: More than 5 equal bits in a sequence have occurred in a part of a received message where this is not allowed.
2= Form Error: A fixed format part of a received frame has the wrong format.
3= AckError: The message transmitted by the M_TTCAN was not acknowledged by another node.
4= Bit1Error: During the transmission of a message (with the exception of the arbitration field),
the device wanted to send a recessive level (bit of logical value '1'), but the monitored bus
value was dominant.
5= Bit0Error: During the transmission of a message (or acknowledge bit, or active error flag, or
overload flag), the device wanted to send a dominant level (data or identifier bit logical value
0'), but the monitored bus value was recessive. During Bus_Off recovery this status is set
each time a sequence of 11 recessive bits has been monitored. This enables the CPU to
monitor the proceeding of the Bus_Off recovery sequence (indicating the bus is not stuck at
dominant or continuously disturbed).
6= CRCError: The CRC check sum of a received message was incorrect. The CRC of an incoming
message does not match with the CRC calculated from the received data.
7= NoChange: Any read access to the Protocol Status Register re-initializes the LEC to '7'.

- was not able to write a message to the Message RAM. In this case message storage is aborted.
In both cases the FIFO put index is not updated resp. the New Data flag for a dedicated Rx Buffer is not set, a partly stored message is overwritten when the next message is stored to this location.
The flag is also set when the Tx Handler was not able to read a message from the Message RAM
in time. In this case message transmission is aborted. In case of a Tx Handler access failure the
M_TTCAN is switched into Restricted Operation Mode (see Section 3.1.5). To leave Restricted

TRP
Transmission Request Pending
Each Tx Buffer has its own Transmission Request Pending bit. The bits are set via register TXBAR.
The bits are reset after a requested transmission has completed or has been cancelled via register
TXBCR.
TXBRP bits are set only for those Tx Buffers configured via TXBC. After a TXBRP bit has been set,
a Tx scan (see Section 3.5, Tx Handling) is started to check for the pending Tx request with the
highest priority (Tx Buffer with lowest Message ID).
A cancellation request resets the corresponding transmission request pending bit of register
TXBRP. In case a transmission has already been started when a cancellation is requested, this is
done at the end of the transmission, regardless whether the transmission was successful or not. The
cancellation request bits are reset directly after the corresponding TXBRP bit has been reset.
After a cancellation has been requested, a finished cancellation is signaled via TXBCF
after successful transmission together with the corresponding TXBTO bit
when the transmission has not yet been started at the point of cancellation
when the transmission has been aborted due to lost arbitration
when an error occurred during frame transmission
In DAR mode all transmissions are automatically cancelled if they are not successful. The
corresponding TXBCF bit is set for all unsuccessful transmissions.

EC_AM_MODE
Internally clocked mode ('0') or externally clocked mode ('1') address matching (I2C) or selection (SPI). In internally clocked mode, the serial interface protocols run off the peripheral clock. In externally clocked mode, the serial interface protocols run off the clock as provided by the serial interface. Externally clocked mode is only used for synchronous serial interface protocols (SPI and I2C) in slave mode. In SPI mode, only Motorola submode (all Motorola modes: 0, 1, 2, 3) is supported.
In UART mode this field should be '0'.
[8:8]
read-write
EC_OP_MODE
Internally clocked mode ('0') or externally clocked mode ('1') operation. In internally clocked mode, the serial interface protocols run off the peripheral clock. In externally clocked mode, the serial interface protocols run off the clock as provided by the serial interface. Externally clocked operation mode is only used for synchronous serial interface protocols (SPI and I2C) in slave mode AND EZ mode. In SPI mode, only Motorola submode (all Motorola modes: 0, 1, 2, 3) is supported. The maximum SPI slave, EZ mode bitrate is 48 Mbps (transmission and IO delays outside the IP will degrade the effective bitrate).
In UART mode this field should be '0'.
[9:9]
read-write
EZ_MODE
Non EZ mode ('0') or EZ mode ('1'). In EZ mode, a meta protocol is applied to the serial interface protocol. This meta protocol adds meaning to the data frames transferred by the serial interface protocol: a data frame can represent a memory address, a write memory data element or a read memory data element. EZ mode is only used for synchronous serial interface protocols: SPI and I2C. In SPI mode, only Motorola submode (all Motorola modes: 0, 1, 2, 3) is supported and the transmitter should use continuous data frames; i.e. data frames mot separated by slave deselection. This mode is only applicable to slave functionality. In EZ mode, the slave can read from and write to an addressable memory structure of up to 256 bytes. In EZ mode, data frames should 8-bit in size and should be transmitted and received with the Most Significant Bit (MSB) first.
In UART mode this field should be '0'.

BYTE_MODE
Determines the number of bits per FIFO data element:
'0': 16-bit FIFO data elements.
'1': 8-bit FIFO data elements. This mode doubles the amount of FIFO entries, but TX_CTRL.DATA_WIDTH and RX_CTRL.DATA_WIDTH are restricted to [0, 7].

CMD_RESP_MODE
Determines CMD_RESP mode of operation:
'0': CMD_RESP mode disabled.

[12:12]
read-write
ADDR_ACCEPT
Determines whether a received matching address is accepted in the RX FIFO ('1') or not ('0').
In I2C mode, this field is used to allow the slave to put the received slave address or general call address in the RX FIFO. Note that a received matching address is put in the RX FIFO when ADDR_ACCEPT is '1' for both I2C read and write transfers.
In multi-processor UART receiver mode, this field is used to allow the receiver to put the received address in the RX FIFO. Note: non-matching addresses are never put in the RX FIFO.
[16:16]
read-write
BLOCK
Only used in externally clocked mode. If the externally clocked logic and the MMIO SW accesses to EZ memory coincide/collide, this bit determines whether a SW access should block and result in bus wait states ('BLOCK is 1') or not (BLOCK is '0'). IF BLOCK is '0' and the accesses collide, MMIO read operations return 0xffff:ffff and MMIO write operations are ignored. Colliding accesses are registered as interrupt causes: field BLOCKED of MMIO registers INTR_TX and INTR_RX.

ENABLED
IP enabled ('1') or not ('0'). The proper order in which to initialize the IP is as follows:
- Program protocol specific information using SPI_CTRL, UART_CTRL (and UART_TX_CTRL and UART_RX_CTRL) or I2C_CTRL. This includes selection of a submode, master/slave functionality and transmitter/receiver functionality when applicable.
- Program generic transmitter (TX_CTRL) and receiver (RX_CTRL) information. This includes enabling of the transmitter and receiver functionality.
- Program transmitter FIFO (TX_FIFO_CTRL) and receiver FIFO (RX_FIFO_CTRL) information.
- Program CTRL to enable IP, select the specific operation mode and oversampling factor.
When the IP is enabled, no control information should be changed. Changes should be made AFTER disabling the IP, e.g. to modify the operation mode (from I2C to SPI) or to go from externally to internally clocked. The change takes effect after the IP is re-enabled. Note that disabling the IP will cause re-initialization of the design and associated state is lost (e.g. FIFO content).

SSEL_CONTINUOUS
Continuous SPI data transfers enabled ('1') or not ('0'). This field is used in master mode. In slave mode, both continuous and non-continuous SPI data transfers are supported independent of this field.
When continuous transfers are enabled individual data frame transfers are not necessarily separated by slave deselection (as indicated by the level or pulse on the SELECT line): if the TX FIFO has multiple data frames, data frames are send out without slave deselection.
When continuous transfers are not enabled individual data frame transfers are always separated by slave deselection: independent of the availability of TX FIFO data frames.

CPHA
Indicates the clock phase. This field, together with the CPOL field, indicates when MOSI data is driven and MISO data is captured:
- Motorola mode 0. CPOL is '0', CPHA is '0': MOSI is driven on a falling edge of SCLK. MISO is captured on a rising edge of SCLK.
- Motorola mode 1. CPOL is '0', CPHA is '1': MOSI is driven on a rising edge of SCLK. MISO is captured on a falling edge of SCLK.

When '0', the default applies (for Motorola as determined by CPOL and CPHA, for Texas Instruments on the falling edge of SCLK and for National Semiconductors on the rising edge of SCLK).
When '1', the alternate clock edge is used (which comes half a SPI SCLK period later). Late sampling addresses the round trip delay associated with transmitting SCLK from the master to the slave and transmitting MISO from the slave to the master.

MP_MODE
Multi-processor mode. When '1', multi-processor mode is enabled. In this mode, RX_CTRL.DATA_WIDTH should indicate a 9-bit data frame. In multi-processor mode, the 9th received bit of a data frame separates addresses (bit is '1') from data (bit is '0'). A received address is matched with RX_MATCH.DATA and RX_MATCH.MASK. In the case of a match, subsequent received data are sent to the RX FIFO. In the case of NO match, subsequent received data are dropped.
[10:10]
read-write
LIN_MODE
Only applicable in standard UART submode. When '1', the receiver performs break detection and baud rate detection on the incoming data. First, break detection counts the amount of bit periods that have a line value of '0'. BREAK_WIDTH specifies the minimum required amount of bit periods. Successful break detection sets the INTR_RX.BREAK_DETECT interrupt cause to '1'. Second, baud rate detection counts the amount of peripheral clock periods that are use to receive the synchronization byte (0x55; least significant bit first). The count is available through UART_RX_STATUS.BR_COUNTER. Successful baud rate detection sets the INTR_RX.BAUD_DETECT interrupt cause to '1' (BR_COUNTER is reliable). This functionality is used to synchronize/refine the receiver clock to the transmitter clock. The receiver software can use the BR_COUNTER value to set the right IP clock (from the programmable clock IP) to guarantee successful receipt of the first LIN data frame (Protected Identifier Field) after the synchronization byte.
[12:12]
read-write
SKIP_START
Only applicable in standard UART submode. When '1', the receiver skips start bit detection for the first received data frame. Instead, it synchronizes on the first received data frame bit, which should be a '1'. This functionality is intended for wake up from DeepSleep when receiving a data frame. The transition from idle ('1') to START ('0') on the RX line is used to wake up the CPU. The transition detection (and the associated wake up functionality) is performed by the GPIO2 IP. The woken up CPU will enable the SCB's UART receiver functionality. Once enabled, it is assumed that the START bit is ongoing (the CPU wakeup and SCB enable time should be less than the START bit period). The SCB will synchronize to a '0' to '1' transition, which indicates the first data frame bit is received (first data frame bit should be '1'). After synchronization to the first data frame bit, the SCB will resume normal UART functionality: subsequent data frames will be synchronized on the receipt of a START bit.
[13:13]
read-write
BREAK_WIDTH
Break width. BREAK_WIDTH + 1 is the minimum width in bit periods of a break. During a break the transmitted/received line value is '0'. This feature is useful for standard UART submode and LIN submode ('break field' detection). Once, the break is detected, the INTR_RX.BREAK_DETECT bit is set to '1'. Note that break detection precedes baud rate detection, which is used to synchronize/refine the receiver clock to the transmitter clock. As a result, break detection operates with an unsynchronized/unrefined receiver clock. Therefore, the receiver's definition of a bit period is imprecise and the setting of this field should take this imprecision into account. The LIN standard also accounts for this imprecision: a LIN start bit followed by 8 data bits allows for up to 9 consecutive '0' bit periods during regular transmission, whereas the LIN break detection should be at least 13 consecutive '0' bit periods. This provides for a margin of 4 bit periods. Therefore, the default value of this field is set to 10, representing a minimal break field with of 10+1 = 11 bit periods; a value in between the 9 consecutive bit periods of a regular transmission and the 13 consecutive bit periods of a break field. This provides for slight imprecisions of the receiver clock wrt. the transmitter clock. There should not be a need to program this field to any value other than its default value.

For internally clocked logic (EC_AM is '0' and EC_OP is '0') on an address match or general call address (and S_GENERAL_IGNORE is '0'). Only used when:
- EC_AM is '0', EC_OP is '0' and non EZ mode.
Functionality is as follows:
- 1: a received (matching) slave address is immediately NACK'd when the receiver FIFO is full.
- 0: clock stretching is performed (till the receiver FIFO is no longer full).
For externally clocked logic (EC_AM is '1') on an address match or general call address (and S_GENERAL_IGNORE is '0'). Only used when (NOT used when EC_AM is '1' and EC_OP is '1' and address match and EZ mode):
- EC_AM is '1' and EC_OP is '0'.
- EC_AM is '1' and general call address match.
- EC_AM is '1' and non EZ mode.
Functionality is as follows:
- 1: a received (matching or general) slave address is always immediately NACK'd. There are two possibilities: 1). the internally clocked logic is enabled (we are in Active system power mode) and it handles the rest of the current transfer. In this case the I2C master will not observe the NACK. 2). the internally clocked logic is not enabled (we are in DeepSleep system power mode). In this case the I2C master will observe the NACK and may retry the transfer in the future (which gives the internally clocked logic the time to wake up from DeepSleep system power mode).
- 0: clock stretching is performed (till the internally clocked logic takes over). The internally clocked logic will handle the ongoing transfer as soon as it is enabled.

S_NOT_READY_DATA_NACK
For internally clocked logic only. Only used when:

- 0: clock stretching is performed (till the receiver FIFO is no longer full).

LOOPBACK
Local loopback control (does NOT affect the information on the pins). Only applicable in master/slave mode. When '0', the I2C SCL and SDA lines are connected to the I2C SCL and SDA pins. When '1', I2C SCL and SDA lines are routed internally in the peripheral, and as a result unaffected by other I2C devices. This allows a SCB I2C peripheral to address itself.

BUS_BUSY
I2C bus is busy. The bus is considered busy ('1'), from the time a START is detected or from the time the SCL line is '0'. The bus is considered idle ('0'), from the time a STOP is detected. If the IP is disabled, BUS_BUSY is '0'. After enabling the IP, it takes time for the BUS_BUSY to detect a busy bus. This time is the maximum high time of the SCL line. For a 100 kHz interface frequency, this maximum high time may last roughly 5 us (half a bit period).
For single master systems, BUS_BUSY does not have to be used to detect an idle bus before a master starts a transfer using I2C_M_CMD.M_START (no bus collisions).
For multi-master systems, BUS_BUSY can be used to detect an idle bus before a master starts a transfer using I2C_M_CMD.M_START_ON_IDLE (to prevent bus collisions).

M_START
When '1', transmit a START or REPEATED START. Whether a START or REPEATED START is transmitted depends on the state of the master state machine. A START is only transmitted when the master state machine is in the default state. A REPEATED START is transmitted when the master state machine is not in the default state, but is working on an ongoing transaction. The REPEATED START can only be transmitted after a NACK or ACK has been received for a transmitted data element or after a NACK has been transmitted for a received data element. When this action is performed, the hardware sets this field to '0'.

read-write
M_START_ON_IDLE
When '1', transmit a START as soon as the bus is idle (I2C_STATUS.BUS_BUSY is '0', note that BUSY has a default value of '0'). For bus idle detection the hardware relies on STOP detection. As a result, bus idle detection is only functional after at least one I2C bus transfer has been detected on the bus (default/reset value of BUSY is '0') . A START is only transmitted when the master state machine is in the default state. When this action is performed, the hardware sets this field to '0'.

OPEN_DRAIN
Each IO cell 'xxx' has two associated IP output signals 'xxx_out_en' and 'xxx_out'.
'0': Normal operation mode. Typically, this operation mode is used for IO cells that are connected to (board) wires/lines that are driven by a single IO cell. In this operation mode, for an IO cell 'xxx' that is used as an output, the 'xxx_out_en' output enable signal is typically constant '1' the 'xxx_out' output is the outputted value. In other words, in normal operation mode, the 'xxx_out' output is used to control the IO cell output value: 'xxx_out' is '0' to drive an IO cell output value of '0' and 'xxx_out' is '1' to drive an IO cell output value of '1'.
'1': Open drain operation mode. Typically this operation mode is used for IO cells that are connected to (board) wires/lines that are driven by multiple IO cells (possibly on multiple chips). In this operation mode, for and IO cell 'xxx' that is used as an output, the 'xxx_out_en' output controls the outputted value. Typically, open drain operation mode drives low/'0' and the 'xxx_out' output is constant '1'. In other words, in open drain operation mode, the 'xxx_out_en' output is used to control the IO cell output value: in drive low/'0' mode: 'xxx_out_en' is '1' (drive enabled) to drive an IO cell output value of '0' and 'xxx_out_en' is '1' (drive disabled) to not drive an IO cell output value (another IO cell can drive the wire/line or a pull up results in a wire/line value '1').
The open drain mode is supported for:
- I2C mode, 'i2c_scl' and 'i2c_sda' IO cells.
- UART mode, 'uart_tx' IO cell.
- SPI mode, 'spi_miso' IO cell.

DATA
Data read from the receiver FIFO. Reading a data frame will remove the data frame from the FIFO; i.e. behavior is similar to that of a POP operation. Note that when CTRL.BYTE_MODE is '1', only DATA[7:0] are used.
This register has a side effect when read by software: a data frame is removed from the FIFO. This may be undesirable during debug; i.e. a read during debug should NOT have a side effect. To this end, the IP uses the AHB-Lite 'hmaster[0]' input signal. When this signal is '1' in the address cycle of a bus transfer, a read transfer will not have a side effect. As a result, a read from this register will not remove a data frame from the FIFO. As a result, a read from this register behaves as a read from the SCB_RX_FIFO_RD_SILENT register.
A read from an empty RX FIFO sets INTR_RX.UNDERFLOW to '1'.

I2C_ARB_LOST
I2C slave lost arbitration: the value driven on the SDA line is not the same as the value observed on the SDA line (while the SCL line is '1'). This should not occur, it represents erroneous I2C bus behavior. In case of lost arbitration, the I2C slave state machine abort the ongoing transfer. The Firmware may decide to clear the TX and RX FIFOs in case of this error.

I2C_NACK
I2C slave negative acknowledgement received. Set to '1', when the slave receives a NACK (typically after the slave transmitted TX data).

[2:2]
read-write
I2C_WRITE_STOP
I2C STOP event for I2C write transfer intended for this slave (address matching is performed). Set to '1', when STOP or REPEATED START event is detected. The REPEATED START event is included in this interrupt cause such that the I2C transfers separated by a REPEATED START can be distinguished and potentially treated separately by the Firmware. Note that the second I2C transfer (after a REPEATED START) may be to a different slave address.
In non EZ mode, the event is detected on any I2C write transfer intended for this slave. Note that a I2C write address intended for the slave (address is matching and a it is a write transfer) will result in a I2C_WRITE_STOP event independent of whether the I2C address is ACK'd or NACK'd.
In EZ mode, the event is detected only on I2C write transfers that have EZ data written to the memory structure (an I2C write transfer that only communicates an I2C address and EZ address, will not result in this event being detected).
[3:3]
read-write
I2C_STOP
I2C STOP event for I2C (read or write) transfer intended for this slave (address matching is performed). Set to '1', when STOP or REPEATED START event is detected. The REPEATED START event is included in this interrupt cause such that the I2C transfers separated by a REPEATED START can be distinguished and potentially treated separately by the Firmware. Note that the second I2C transfer (after a REPEATED START) may be to a different slave address.
The event is detected on any I2C transfer intended for this slave. Note that a I2C address intended for the slave (address is matching) will result in a I2C_STOP event independent of whether the I2C address is ACK'd or NACK'd.
[4:4]
read-write
I2C_START
I2C slave START received. Set to '1', when START or REPEATED START event is detected.
In the case of externally clocked address matching (CTRL.EC_AM_MODE is '1') AND clock stretching is performed (till the internally clocked logic takes over) (I2C_CTRL.S_NOT_READY_ADDR_NACK is '0'), this field is NOT set. The Firmware should use INTR_S_EC.WAKE_UP, INTR_S.I2C_ADDR_MATCH and INTR_S.I2C_GENERAL.
[5:5]
read-write
I2C_ADDR_MATCH
I2C slave matching address received. If CTRL.ADDR_ACCEPT, the received address (including the R/W bit) is available in the RX FIFO. In the case of externally clocked address matching (CTRL.EC_AM_MODE is '1') and internally clocked operation (CTRL.EC_OP_MODE is '0'), this field is set when the event is detected.
[6:6]
read-write
I2C_GENERAL
I2C slave general call address received. If CTRL.ADDR_ACCEPT, the received address 0x00 (including the R/W bit) is available in the RX FIFO. In the case of externally clocked address matching (CTRL.EC_AM_MODE is '1') and internally clocked operation (CTRL.EC_OP_MODE is '0'), this field is set when the event is detected.

I2C_BUS_ERROR
I2C slave bus error (unexpected detection of START or STOP condition). This should not occur, it represents erroneous I2C bus behavior. In case of a bus error, the I2C slave state machine abort the ongoing transfer. The Firmware may decide to clear the TX and RX FIFOs in case of this error.

FRAME_ERROR
Frame error in received data frame. Set to '1', when event is detected. Write with '1' to clear bit. This can be either a start or stop bit(s) error:
Start bit error: after the detection of the beginning of a start bit period (RX line changes from '1' to '0'), the middle of the start bit period is sampled erroneously (RX line is '1'). Note: a start bit error is detected BEFORE a data frame is received.
Stop bit error: the RX line is sampled as '0', but a '1' was expected. Note: a stop bit error may result in failure to receive successive data frame(s). Note: a stop bit error is detected AFTER a data frame is received.
A stop bit error is detected after a data frame is received, and the UART_RX_CTL.DROP_ON_FRAME_ERROR field specifies whether the received frame is dropped or send to the RX FIFO. If UART_RX_CTL.DROP_ON_FRAME_ERROR is '1', the received data frame is dropped. If UART_RX_CTL.DROP_ON_FRAME_ERROR is '0', the received data frame is send to the RX FIFO. Note that Firmware can only identify the erroneous data frame in the RX FIFO if it is fast enough to read the data frame before the hardware writes a next data frame into the RX FIFO; i.e. the RX FIFO does not have error flags to tag erroneous data frames.
[8:8]
read-write
PARITY_ERROR
Parity error in received data frame. Set to '1', when event is detected. Write with '1' to clear bit. If UART_RX_CTL.DROP_ON_PARITY_ERROR is '1', the received frame is dropped. If UART_RX_CTL.DROP_ON_PARITY_ERROR is '0', the received frame is send to the RX FIFO. In SmartCard submode, negatively acknowledged data frames generate a parity error. Note that Firmware can only identify the erroneous data frame in the RX FIFO if it is fast enough to read the data frame before the hardware writes a next data frame into the RX FIFO.
[9:9]
read-write
BAUD_DETECT
LIN baudrate detection is completed. The receiver software uses the UART_RX_STATUS.BR_COUNTER value to set the right IP clock (from the programmable clock IP) to guarantee successful receipt of the first LIN data frame (Protected Identifier Field) after the synchronization byte. Set to '1', when event is detected. Write with '1' to clear bit.
[10:10]
read-write
BREAK_DETECT
Break detection is successful: the line is '0' for UART_RX_CTRL.BREAK_WIDTH + 1 bit period. Can occur at any time to address unanticipated break fields; i.e. 'break-in-data' is supported. This feature is supported for the UART standard and LIN submodes. For the UART standard submodes, ongoing receipt of data frames is NOT affected; i.e. Firmware is expected to take the proper action. For the LIN submode, possible ongoing receipt of a data frame is stopped and the (partially) received data frame is dropped and baud rate detection is started. Set to '1', when event is detected. Write with '1' to clear bit.

AVG_CNT
Averaging Count for channels that have averaging enabled (AVG_EN). A channel will be sampled (1<<(AVG_CNT+1)) = [2..256] times.
- In ACCUNDUMP mode (1st order accumulate and dump filter) a channel will be sampled back to back, the average result is calculated and stored and then the next enabled channel is sampled. If shifting is not enabled (AVG_SHIFT=0) then the result is forced to shift right so that is fits in 16 bits, so right shift is done by max(0,AVG_CNT-3).
- In INTERLEAVED mode one sample is taken per triggered scan, only in the scan where the final averaging count is reached a valid average is calculated and stored in the RESULT register (by definition the same scan for all the channels that have averaging enabled). In all other scans the RESULT register for averaged channels will have an invalid result and the intermediate accumulated value is stored in the 16-bit WORK register. In this mode make sure that the averaging count is low enough to ensure that the intermediate value does not exceed 16-bits otherwise the MSBs will be lost. So for a 12-bit resolution the averaging count should be set to 16 or less (AVG_CNT=<3).

Scheduled UABs: All UABs scanned by the SAR are assumed to be properly scheduled, i.e. their output is assumed to be valid when sampled by the SAR and the SAR does not wait. In this mode the length of the SAR scan is constant.
This mode requires that the SAR scans strictly periodically, i.e. the SAR has to either run continuously or has to be triggered by a periodic hardware trigger (TCPWM or UDB timer). It also requires that the end of the UAB valid phase is precisely aligned with the end of the SAR sample period (using UAB.STARTUP_DELAY). Normally this scheduling is done by Creator.

REPEAT_INVALID
For unscheduled UAB_SCAN_MODE only, do the following if an invalid sample is received:
- 0: use the last known valid sample for that channel and clear the NEWVALUE flag
- 1: repeat the conversions until a valid sample is received (caveat: could be never if the UAB valid window is incorrectly schedule w.r.t. SAR sampling)

DUTY_CYCLE_SAR_ACT_EN
Enable for powering down (duty cycling) a SAR in chip active mode. This is a risk mitigation bit for power reduction in chip active mode. In order for this field affect SAR operation, the SAR must be configured for deepsleep clocking (SAR_CLOCK_SEL.CLOCK_SEL set to 1), and the SAR must be set for Timer-based hardware triggering (either by following the guidlines in SAR_OVR_CTRL.HW_TR_TIMER_SEL or SAR_SIMULT_CTRL.SIMULT_HW_TIMER_SEL).
If this bit is set for a given SAR, the Timer is the only valid trigger source. Non-timer based Hardware (DSI) triggers cannot be used nor can Firmware based triggers (FW,Continuous,Injection). Furthermore, trigger collision functionality will be limited to interrupt generation only.
