9.7.1.2 Automatic Mode
In automatic mode, the PWM(s) are disabled immediately once a filtered
fault condition is detected (logic high). The PWM(s) remain disabled until
the filtered fault condition is cleared (logic low) and a new PWM cycle
begins as shown in
fault condition is detected (logic high). The PWM(s) remain disabled until

. Clearing the corresponding FFLAGx
event bit will not enable the PWMs in automatic mode.
