GPIOTE unavailable on GPIO2 of nRF54L15 ?https://devzone.nordicsemi.com/f/nordic-q-a/123953/gpiote-unavailable-on-gpio2-of-nrf54l15Hello, I&#39;ve recently purchased the Xiao nRF54L15 development board, along with the Xiao CAN bus expansion board. However, it seems that these board are not entirely compatible...? What I mean is that the interrupt pin for the MCP2515 on the CAN busen-USTelligent Community 13Wed, 27 Aug 2025 19:17:39 GMTRE: GPIOTE unavailable on GPIO2 of nRF54L15 ?https://devzone.nordicsemi.com/thread/546976?ContentTypeID=1Wed, 27 Aug 2025 19:17:39 GMT137ad170-7792-4731-bb38-c0d22fbe4515:cbaf844a-2f36-4fc9-aa33-68ac71d286c9Vince C<p>Hi SwRa,<br /><br />Got it.</p> <p>It seems Seeed Studio may have overlooked this detail.

This is stated in the documentation: &quot;</span>P2 pins cannot wake the system from sleep, and it does not include the GPIO SENSE or DETECT mechanism or GPIOTE functionality. This means that interrupt support is not available on P2 pins when they are configured as general-purpose GPIO.&quot; See <a href="https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/essential-pin-planning-guidelines-for-the-nrf54l-series#mcetoc_1ithovivb1:~:text=P2%20pins%20cannot%20wake%20the%20system%20from%20sleep%2C%20and%20it%20does%20not%20include%20the%20GPIO%20SENSE%20or%20DETECT%20mechanism%20or%20GPIOTE%20functionality.%20This%20means%20that%20interrupt%20support%20is%20not%20available%20on%20P2%20pins%20when%20they%20are%20configured%20as%20general%2Dpurpose%20GPIO.">here</a>.&nbsp;</p> <p><span>If you need interrupt capability for the MCP2515, you must connect its interrupt output to a pin on P1 or P0, which do support GPIOTE and interrupts.</span></p> <p><span>Regards,</span></p> <p><span>Swathy</span></p><div style="clear:both;"></div>
