27 ##### SDMMC peripheral features #####
28 ==============================================================================
29 [..] The SD/SDMMC MMC card host interface (SDMMC) provides an interface between the AHB
30 peripheral bus and MultiMedia cards (MMCs), SD memory cards, SDMMC cards and CE-ATA
31 devices.
32
33 [..] The SDMMC features include the following:
34 (+) Full compliance with MultiMediaCard System Specification Version 4.51. Card support
35 for three different databus modes: 1-bit (default), 4-bit and 8-bit.
36 (+) Full compatibility with previous versions of MultiMediaCards (backward compatibility).
37 (+) Full compliance with SD memory card specifications version 4.1.
38 (SDR104 SDMMC_CK speed limited to maximum allowed IO speed, SPI mode and
39 UHS-II mode not supported).
40 (+) Full compliance with SDIO card specification version 4.0. Card support
41 for two different databus modes: 1-bit (default) and 4-bit.
42 (SDR104 SDMMC_CK speed limited to maximum allowed IO speed, SPI mode and
43 UHS-II mode not supported).
44 (+) Data transfer up to 208 Mbyte/s for the 8 bit mode. (depending maximum allowed IO speed).
45 (+) Data and command output enable signals to control external bidirectional drivers
46
47 ##### How to use this driver #####
48 ==============================================================================
49 [..]
50 This driver is a considered as a driver of service for external devices drivers
51 that interfaces with the SDMMC peripheral.
52 According to the device used (SD card/ MMC card / SDMMC card ...), a set of APIs
53 is used in the device's driver to perform SDMMC operations and functionalities.
54
55 This driver is almost transparent for the final user, it is only used to implement other
56 functionalities of the external device.
57
58 [..]
59 (+) The SDMMC clock is coming from output of PLL1_Q or PLL2_R.
60 Before start working with SDMMC peripheral make sure that the PLL is well configured.
61 The SDMMC peripheral uses two clock signals:
62 (++) PLL1_Q bus clock (default after reset)
63 (++) PLL2_R bus clock
64
65 (+) Enable/Disable peripheral clock using RCC peripheral macros related to SDMMC
66 peripheral.
67
68 (+) Enable the Power ON State using the SDMMC_PowerState_ON(SDMMCx)
69 function and disable it using the function SDMMC_PowerState_OFF(SDMMCx).
70
71 (+) Enable/Disable the peripheral interrupts using the macros __SDMMC_ENABLE_IT(hSDMMC, IT)
72 and __SDMMC_DISABLE_IT(hSDMMC, IT) if you need to use interrupt mode.
73
74 (+) When using the DMA mode
75 (++) Configure the IDMA mode (Single buffer or double)
76 (++) Configure the buffer address
77 (++) Configure Data Path State Machine
78
79 (+) To control the CPSM (Command Path State Machine) and send
80 commands to the card use the SDMMC_SendCommand(SDMMCx),
81 SDMMC_GetCommandResponse() and SDMMC_GetResponse() functions. First, user has
82 to fill the command structure (pointer to SDMMC_CmdInitTypeDef) according
83 to the selected command to be sent.
84 The parameters that should be filled are:
85 (++) Command Argument
86 (++) Command Index
87 (++) Command Response type
88 (++) Command Wait
89 (++) CPSM Status (Enable or Disable).
90
91 -@@- To check if the command is well received, read the SDMMC_CMDRESP
92 register using the SDMMC_GetCommandResponse().
93 The SDMMC responses registers (SDMMC_RESP1 to SDMMC_RESP2), use the
94 SDMMC_GetResponse() function.
95
96 (+) To control the DPSM (Data Path State Machine) and send/receive
97 data to/from the card use the SDMMC_DataConfig(), SDMMC_GetDataCounter(),
98 SDMMC_ReadFIFO(), SDMMC_WriteFIFO() and SDMMC_GetFIFOCount() functions.
99
100 *** Read Operations ***
101 =======================
102 [..]
103 (#) First, user has to fill the data structure (pointer to
104 SDMMC_DataInitTypeDef) according to the selected data type to be received.
105 The parameters that should be filled are:
106 (++) Data TimeOut
107 (++) Data Length
108 (++) Data Block size
109 (++) Data Transfer direction: should be from card (To SDMMC)
110 (++) Data Transfer mode
111 (++) DPSM Status (Enable or Disable)
112
113 (#) Configure the SDMMC resources to receive the data from the card
114 according to selected transfer mode (Refer to Step 8, 9 and 10).
115
116 (#) Send the selected Read command (refer to step 11).
117
118 (#) Use the SDMMC flags/interrupts to check the transfer status.
119
120 *** Write Operations ***
121 ========================
122 [..]
123 (#) First, user has to fill the data structure (pointer to
124 SDMMC_DataInitTypeDef) according to the selected data type to be received.
125 The parameters that should be filled are:
126 (++) Data TimeOut
127 (++) Data Length
128 (++) Data Block size
129 (++) Data Transfer direction: should be to card (To CARD)
130 (++) Data Transfer mode
131 (++) DPSM Status (Enable or Disable)
132
133 (#) Configure the SDMMC resources to send the data to the card according to
134 selected transfer mode.
135
136 (#) Send the selected Write command.
137
138 (#) Use the SDMMC flags/interrupts to check the transfer status.
139
140 *** Command management operations ***
141 =====================================
142 [..]
143 (#) The commands used for Read/Write/Erase operations are managed in
144 separate functions.
145 Each function allows to send the needed command with the related argument,
146 then check the response.
147 By the same approach, you could implement a command and check the response.
