If not what is the state of the GPIO pins during startup?en-USTelligent Community 13Tue, 15 Mar 2016 14:41:54 GMThttps://devzone.nordicsemi.com/thread/47672?ContentTypeID=1Tue, 15 Mar 2016 14:41:54 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ba900c85-5b16-463e-9529-9df06440205dHung Bui<p>Hi Ronny,</p> <p>Yes, except for wake up reset from SystemOFF mode, when starting up the GPIO pin will be in input mode, but input buffer is disconnected. So basically it&#39;s a floating pin with high impedance.</p> <p>If waking up from SystemOFF the GPIO pins will keep the previous configured state.</p><div style="clear:both;"></div>
