https://devzone.nordicsemi.com/f/nordic-q-a/109/nrf24le1I want to know the EXT interrupt (GPINT1 &amp; GPINT0) can use at the same time. When I use the GPINT1 &amp; GPINT0 at the same time,only one is OK the other is faile.en-USTelligent Community 13Tue, 23 Jul 2013 09:40:03 GMThttps://devzone.nordicsemi.com/thread/604?ContentTypeID=1Tue, 23 Jul 2013 09:40:03 GMT137ad170-7792-4731-bb38-c0d22fbe4515:87ea8801-4bd5-490d-a24b-7451a334c226H&#229;kon Alseth<p>Hi,</p> <p>Unfortunately, the GPINTx is not functional when enabling more than one.</p> <p>If you enable two or more, there is a &quot;logic and&quot; to trigger the interrupt, meaning that all sources must be active at the same time in order to trigger the interrupt. This is a feature with this specific peripheral. Also mentioned in chapter 9.3 of the spec: [i]Interrupt from pin GP INT0, GP INT1 or GP INT2 as selected by bits 3,4 or 5 in SFR INTEXP. Only one of the bits may be set at a time.[/i]</p> <p>A workaround can be to poll the lines using the RTC interrupt.</p> <p>Best regards Håkon</p><div style="clear:both;"></div>
