Pulse-Width Modulator for Motor Control (PWMMC)
This read/write bit allows the CPU interrupt caused by faults on fault
pin 4 to be enabled. The fault protection circuitry is independent of this
bit and will always be active. If a fault is detected, the PWM pins will
still be disabled according to the disable mapping register.
This read/write bit allows the user to select between automatic and
manual mode faults. For further descriptions of each mode,

This read/write bit allows the CPU interrupt caused by faults on fault

still be disabled according to the disable mapping register.
1 = Fault pin 4 will cause CPU interrupts.
0 = Fault pin 4 will not cause CPU interrupts.
1 = Automatic mode
0 = Manual mode
1 = Fault pin 3 will cause CPU interrupts.
0 = Fault pin 3 will not cause CPU interrupts.
