nRF52840 read GPIO state right after its wakeup from deep sleephttps://devzone.nordicsemi.com/f/nordic-q-a/112001/nrf52840-read-gpio-state-right-after-its-wakeup-from-deep-sleepI am trying to read the GPIO state on an nRF52840 right after it wakes up from deep sleep (System OFF mode). I have configured 4 pins as wake-up sources from deep sleep System OFF mode. I tried using the latch register, but it does not work at all.

It was due to RTT debug mode. When debug mode is not enabled and we read logs over UART, the pins&#39; state reads fine after a reset.</p> </div> </div> </div> </div> <div class="mt-1 flex gap-3 empty:hidden juice:-ml-3"> <div class="items-center justify-start rounded-xl p-1 flex"> <div class="flex items-center"> <div class="flex items-center pb-0.5 juice:pb-0"><span class="line-clamp-1 text-sm"></span></div> </div> </div> </div><div style="clear:both;"></div>RE: nRF52840 read GPIO state right after its wakeup from deep sleephttps://devzone.nordicsemi.com/thread/488483?ContentTypeID=1Wed, 12 Jun 2024 11:44:01 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4e1389dd-e99b-49c4-adbb-76c21a76418dNaeem Maroof<p>Hi Bilal,</p> <p>Can you show your implementation (probably a project zip that would build correctly)? I will test at my end and hook up logic analyzer to see it pins are low or are not detected.</p><div style="clear:both;"></div>
