https://devzone.nordicsemi.com/f/nordic-q-a/78146/nrf5340---resetreasHi, I wanted nRF5340 capable of reporting the VDD under-voltage event causing a pin reset through a dedicated voltage monitoring IC. For this reason I put a Flip-Flop for storing and making this information available via GPIO on subsequent reboot.

This will contain information if the reset is due to a pin reset, or a BOR (brown out reset) if the voltage was too low, or other things.</p><div style="clear:both;"></div>
