Hi, we have been testing a design based on a MSPM0L1105TRHBR, we are finding that the MCU locks up under certain battery bounce sequences.
This should not be possible due to the hardware POR, but it does appear to be the case regardless.
We have the recommended 47K + 4.7uF reset circuit, and we still experience lockups when dropping a coin cell battery into its receptacle.
Please advise if there is a suitable solution in firmware or hardware.
Example VCC waveform which triggers the issue (time axis is in seconds, full waveform is around 100ms):
