Table 17.
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 paragraph
When when SYNC_EN bit is set low BUSY/SYNC output is forced low during commands
execution, otherwise, when SYNC_EN bit is set high, BUSY/SYNC output provides a clock
signal according to SYNC_SEL parameter.
