PWM Fault Control Register
The PWM Fault Control (PWMFCTL) Register, shown in Table 54, determines how the
PWM recovers from a fault condition. Settings in this register select automatic or software
controlled PWM restart.

Description
Reserved.
DebugRestart
Automatic recovery. PWM resumes control of outputs when all fault sources have
deasstered and a new PWM period begins.
Software controlled recovery. PWM resumes control of outputs only after all fault
sources have deasserted and all fault flags are cleared and a PWM reload occurs
Fault 1 Interrupt
Interrupt on comparator assertion disabled.
Interrupt on comparator assertion enabled.
Fault 1 Restart
Automatic recovery. PWM resumes control of outputs when all fault sources have
deasstered.
Software controlled recovery. PWM resumes control of outputs only after all fault
sources have deasserted and all fault flags are cleared and a PWM reload occurs
Comparator 0 Interrupt
Interrupt on comparator 0 assertion disabled.
Interrupt on comparator 0 assertion enabled.
Comparator 0 Restart
Automatic recovery. PWM resumes control of outputs when all fault sources have
deasstered.
Software controlled recovery. PWM resumes control of outputs only after all fault
sources have deasserted and all fault flags are cleared and a PWM reload occurs
