(svmStd3Xor_fault)

The svmStd3Xor_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.
