In this case, you will not be able to use the reset pin. This can only be configured to pin P0.18.&nbsp;</p> <p>Reset is not needed for programming, reset can be done from the SWD interface if needed.</p> <p>Trace is hardwired to a set of pins. If you need trace, you could do that part with the DK instead.&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/138985?ContentTypeID=1Wed, 04 Jul 2018 13:25:52 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d30dcd6b-ed37-491e-a542-734ac47fa327MartinBL<p>Hi,</p> <p>I gave you an answer in the other thread.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/138871?ContentTypeID=1Wed, 04 Jul 2018 03:18:33 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c04811c3-0d8b-44cc-8c75-df27bde751faPatrick Lloyd<p>Accidentally necro-bumped this question here:&nbsp;<a href="https://devzone.nordicsemi.com/f/nordic-q-a/25750/nrf52840-avoid-via-in-pad-by-connecting-pins-together">https://devzone.nordicsemi.com/f/nordic-q-a/25750/nrf52840-avoid-via-in-pad-by-connecting-pins-together</a></p> <p></p> <p>It contains some info but doesn&#39;t address the PSELRESET register question.</p><div style="clear:both;"></div>
