Pulse Width Modulator for Motor Control (PWMMC)
9.7.1 Fault Condition Input Pins
Technical Data
164
A logic high level on a fault pin disables the respective PWM(s)
determined by the bank and the disable mapping register. Each fault pin
incorporates a filter to assist in rejecting spurious faults. All of the
external fault pins are software-configurable to re-enable the PWMs
either with the fault pin (automatic mode) or with software (manual
mode). Each fault pin has an associated FMODE bit to control the PWM
re-enabling method. Automatic mode is selected by setting the FMODEx
bit in the fault control register. Manual mode is selected when FMODEx
is clear.
