https://devzone.nordicsemi.com/f/nordic-q-a/1634/soft-power-on-with-nrf51822I am currently designing a board using the nRF51822 chip and I would like to implement a soft power ON circuit using the low power comparator (LPCOMP). I understand that the LPCOMP uses the analog input AIN0 to 7 as input, but I would like to knowen-USTelligent Community 13Mon, 17 Feb 2014 16:46:19 GMThttps://devzone.nordicsemi.com/thread/7204?ContentTypeID=1Mon, 17 Feb 2014 16:46:19 GMT137ad170-7792-4731-bb38-c0d22fbe4515:eac4289c-87e5-4ad4-adf6-3548d89479f7Janek Mann<p>It won&#39;t be connected to any output pin out of factory (and neither is the input pin). You can to hook up the UP, DOWN, or CROSS event to an output pin using the PPI &amp; GPIOTE peripherals in order to generate a result on a pin.</p><div style="clear:both;"></div>
