The DCmXor_fault is an input TPU function that monitors the pin, and if a high
to low transition occurs, immediately sets all PWM channels low and cancels
all further transitions on them. The PWM channels, as well as the
synchronization and resolver reference signal channels (if used), have to be
initialized again to start them running.
The function returns the actual pinstate as a value of 0 (low) or 1 (high) in the
parameter fault_pinstate. The parameter is placed on the SW1_1 channel to
keep the fault channel parameter space free.
