https://devzone.nordicsemi.com/f/nordic-q-a/1122/enable-and-disable-pheripherals-of-nordicHi, For power critical application, i know that ,we need to enable the peripherals whenever we need that. After we need to disable by using ENABLE register. My question is after disable , is we need t0 reconfigure pin configuration again. en-USTelligent Community 13Mon, 16 Dec 2013 14:50:23 GMThttps://devzone.nordicsemi.com/thread/5250?ContentTypeID=1Mon, 16 Dec 2013 14:50:23 GMT137ad170-7792-4731-bb38-c0d22fbe4515:69d505ac-54b8-42e4-ab3b-490090da85ffH&#229;kon Alseth<p>Hi Balaji,</p> <p>You do not need to reconfigure the TWI-configuration if you enable/disable the peripheral. You only have to reconfigure if you power off the TWI (read: reset the chip)</p> <p>Best regards Håkon</p><div style="clear:both;"></div>
