https://devzone.nordicsemi.com/f/nordic-q-a/65964/nreset-pin-internal-pull-up-disable-p0-18Hello, In our current design, our boards use P0.18 connected to an external watchdog to reset the nRF52840. We configure PSETRESET[0]/[1] to be 0x12 (Connected/enabled on P0.18), and we see the reset functionality works. However, we see there is aen-USTelligent Community 13Wed, 16 Sep 2020 15:50:42 GMThttps://devzone.nordicsemi.com/thread/269923?ContentTypeID=1Wed, 16 Sep 2020 15:50:42 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b68180c6-8d6d-41cc-867a-a4051ceb6754krisburch<p>Thanks Robin</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/269788?ContentTypeID=1Wed, 16 Sep 2020 08:42:24 GMT137ad170-7792-4731-bb38-c0d22fbe4515:61c2e933-acca-4472-bdf5-eec687f232f8Robin M Saltnes<p>Hello krisburch,&nbsp;</p> <p>The internal pullup resistors for reset pins are implemented as a hardwired part of the chip on nRF SoCs. Because of this there is no way of disabling them in software while the pin is configured as a reset.&nbsp;</p> <p>Best regards&nbsp;</p> <p>Robin&nbsp;&nbsp;</p><div style="clear:both;"></div>
