The driver stage can do extended
steps based on XSTEP_OUT
Pulse divisor for XSTEP_OUT output
control
One XSTEP_OUT pulse is generated
after each pulse_xstep_div steps
0: disable STEP_OUT delay
1: enable STEP_OUT delay after a
change of the direction (DIR_OUT)
(It is recommended to disable the
delay, unless a step / direction drive is
used)
