https://devzone.nordicsemi.com/f/nordic-q-a/39984/nrf52840-reset-pin-input-onlyHi there, one quick one: when configured as SYSTEM RESET, Does P0.18 acts as an Input/Output? i.e. will be asserted Low by the NRF52840 while the MCU is in reset? Or is it configured as an input only? Thanks, Mickaelen-USTelligent Community 13Wed, 31 Oct 2018 15:37:49 GMThttps://devzone.nordicsemi.com/thread/155399?ContentTypeID=1Wed, 31 Oct 2018 15:37:49 GMT137ad170-7792-4731-bb38-c0d22fbe4515:fd82de54-306d-4c5e-9501-49f4f113a4edMickael<p>Thanks for confirming.&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/155395?ContentTypeID=1Wed, 31 Oct 2018 15:30:25 GMT137ad170-7792-4731-bb38-c0d22fbe4515:137ac012-8003-47fc-a495-d38b3091ca70Sigurd<p>Hi,</p> [quote user=""]when configured as SYSTEM RESET, Does P0.18 acts as an Input/Output? i.e. will be asserted Low by the NRF52840 while the MCU is in reset?&nbsp;[/quote] <p>&nbsp;It will be a type of input. If you are resetting the chip with e.g. calling&nbsp;NVIC_SystemReset() or with a watchdog timeout, then the reset pin will remain high.</p><div style="clear:both;"></div>
