An additional and optional GPIO, INHC (DWELL) can be used to facilitate the insertion of dwell states or
phase current overlap states between the six commutation steps. This may be used to reduce acoustic noise
and improve motion through the reduction of abrupt current direction changes when switching between states.
INHC must be high when the state is changed and the dwell state will exist until INHC is taken low. If the
dwell states are not being used, the INHC pin can be tied low.
In 1-PWM mode all activity on INLC is ignored.
