Motor Controller Module Stop in Wait Mode
0 Entering wait mode has no effect on the motor controller module and the associated port pins maintain the
1 Entering wait mode will stop the clock of the module and debias the analog circuitry. The
0 PWM operates in 11-bit resolution mode, duty cycle registers of all channels are switched to word mode.
1 PWM operates in 7-bit resolution (fast) mode, duty cycle registers of all channels are switched to byte mode.
0 Dither feature is disabled.
1 Dither feature is enabled.
0 A motor controller timer counter overflow has not occurred since the last reset or since the bit was cleared.
1 A motor controller timer counter overflow has occurred.
