Standard Space Vector Modulation TPU Function Set (svmStd)
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 Phase A – top
channel to keep the fault channel parameter space free.
TPU function svmStd_fault generates an interrupt when a high to low transition
appears.
