STEP_MODE
The STEP_MODE register has the following structure:
Table 19.
1. When the register is written this bit should be set to 1.
Note:
The STEP_SEL parameter selects one of five possible stepping modes:
Table 20.
Every time the step mode is changed, the electrical position (i.e. the point of microstepping
sinewave that is generated) is reset to the first microstep.
Any attempt to write the register when the motor is running causes the command to be
ignored and the NOTPERF_CMD flag to rise (see
When when SYNC_EN bit is set low, BUSY/SYNC output is forced low during the
commands execution, otherwise, when the SYNC_EN bit is set high, the BUSY/SYNC
output provides a clock signal according to the SYNC_SEL parameter.

STEP_MODE register
When the STEP_MODE register is written, the bit #3 is to be set to 1,
otherwise anomalous behaviors could occur.
Step mode selection
STEP_SEL[2..0]
Every time STEP_SEL is changed the value in the ABS_POS
register looses meaning and should be reset.
