6properties:
7  en_spreadcycle:
8    type: boolean
9    description: |
10      A high level on the pin SPREAD inverts this flag to switch between both chopper modes.
11      0: StealthChop mode
12      1: SpreadCycle mode enabled
13
14  i_scale_analog:
15    type: boolean
16    description: |
17      0: Use internal reference derived from 5VOUT
18      1: Use voltage supplied to VREF as current reference
19
20  internal_rsense:
21    type: boolean
22    description: |
23      0: Operation with external sense resistors
24      1: Internal sense resistors. Use current supplied into VREF as reference for internal
25         sense resistor. VREF pin internally is driven to GND in this mode.
26
27  index_otpw:
28    type: boolean
29    description: |
30      0: INDEX shows the first microstep position of sequencer
31      1: INDEX output shows step pulses from internal pulse generator (toggle upon each step)
32
33  index_step:
34    type: boolean
35    description: |
36      0: INDEX output as selected by index_otpw
37      1: INDEX pin shows the current step position of sequencer
38
39  pdn_disable:
40    type: boolean
41    description: |
42      0: Normal operation
43      1: Power down mode
44
45  mstep_reg_select:
46    type: boolean
47    description: |
48      0: Microstep resolution selected by pins MS1, MS2
49      1: Microstep resolution selected by MRES register
50
51  poscmp_enable:
52    type: boolean
53    description: |
54      Enable position compare feature
55      0: Outputs INT and PP are tristated.
56      1: Position compare pulse (PP) and interrupt output (INT) are available
57
58      Attention – do not leave the outputs floating in tristate condition, provide an external
59      pull-up or set poscmp_enable=1
60
61  test_mode:
62    type: boolean
63    description: |
64      Enable test mode
65      0: Normal operation
66      1: Enable analog test output on pin REFR2
67      TEST_SEL selects the function of REFR2: 0…4: T120, DAC1, VDDH1, DAC2, VDDH2
68
69      Attention: Not for user, set to 0 for normal operation!
70
71  lock_gconf:
72    type: boolean
73    description: |
74      1: GCONF is locked against further write access.
