Other Parts Discussed in Thread: TMS570LS3137

I'm using microcontroller is TMS570LS3137.

I'm setting PMM Error-Forcing Mode by " pmmREG->PRCKEYREG = 0x9U;".

So,ESM Group1 Channel38, Group1 Channel38 both flag is set.

What is the cause? Two flags set is no problem ?

HI Arriy,
I think this is expected that both the channel 38 and 39 are set. Since it is a mode to intentionally force an error, the channel 38 is set so the complete path from PMM to ESM is exercised. The channel 39 is set as it is a type of self-test.
