https://devzone.nordicsemi.com/f/nordic-q-a/62782/swo-on-nrf52811-qcaa-qfn32Hi, On page 420 of the nRF52811 datasheet (v1.0) it states that pin 14 (P0.18) can be either 1) Digital I/O or 2) Single wire output (SWO). The SWO is not mentioned on any of the other package types (i.e. QFAA or QAAA), nor is it mentioned in sectionen-USTelligent Community 13Sun, 21 Jun 2020 22:02:26 GMThttps://devzone.nordicsemi.com/thread/256068?ContentTypeID=1Sun, 21 Jun 2020 22:02:26 GMT137ad170-7792-4731-bb38-c0d22fbe4515:65745f51-f3f7-4741-a447-d926223364deNichD<p>Perfect, thanks.&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/255956?ContentTypeID=1Fri, 19 Jun 2020 11:53:25 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2426b5c3-0acc-4681-8d1a-33a17cfe8565haakonsh<p>SWO is an optional debug resource, see&nbsp;<a href="https://wiki.segger.com/SWD">https://wiki.segger.com/SWD</a>.&nbsp;&nbsp;</p> [quote user=""]Thus, should this pin be routed on the PCB to the J-Link programming header (on the QFN32 QCAA) package, or is this an error in the documentation?&nbsp;[/quote] <p>If you want SWO then route it, if not, then don&#39;t.</p> [quote user=""]Secondly, should a 4K7 pull-up resistor be populated on pin 16 if this pin is used as an external RESET pin? [/quote] <p>&nbsp;That&#39;s not necessary, a 13K pull-up is used internally when configured as the RESET pin.</p><div style="clear:both;"></div>
