DESCRIPTION
7
PWM_PDM If PWM_PDM = 0, then motor control in PWM mode. If PWM_PDM = 1, then motor
control in PDM mode.
6
OVF_SW If OVF_SW = 0, then SW1 and SW2 in normal operation. If OVF_SW = 1, then SW1
and SW2 will both open on overflow.
5
SW1 If SW1 = 0, then SW1 is open. If SW1 = 1, then SW1 is closed.
4
SW2 If SW2 = 0, then SW2 is open. If SW2 = 1, then SW2 is closed.
