Hello, recently while debugging some code I saw that sometimes the the interrupt flag for the CLA_UNDERFLOW interrupt is set (PieCtrlRegs.PIEIFR.INT12.bit.16=1). This occurrence is not very consistent. Seems to happen about 1/20 times I run and stop my control routine.
As far as I know, there are two types of under/overflow events associated with the CLA. One is when a peripheral event requests a task which is already running. However, I never see any of my MIOVF bits being set. The other type is somehow related to FPU math operations, but I have very poor understanding of this. I can't find anything in the TRM which refers to the CLA_UNDERFLOW flag, so I don't even know which type of underflow I'm dealing with.
Regards,
Mike
