Embedded Software and Motor Control Libraries for PXR40xx

Function GMCLIB_Park_F32
Note
Both the inverse modulation index pIn->fltModIndex and the
measured DC bus voltage pIn->fltDcBusMsr must be equal to
or greater than 0, otherwise the results are undefined.
4.105.5 Re-entrancy
The function is re-entrant.
