The reset pin has an internal pullup resistor that is enabled automatically if the pin is assigned as a reset pin.&nbsp;</p> <p>regards</p> <p>Jared&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/305353?ContentTypeID=1Sat, 17 Apr 2021 04:15:00 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e0512e75-f916-4190-a620-c02de060e36cFrankBi<p>dears，</p> <p>Yes，I also want to know if need typical RC reset circuit. or as datasheet is ok?</p> <p></p> <p>thanks.&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/305307?ContentTypeID=1Fri, 16 Apr 2021 13:23:13 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0f1949e8-0e08-463e-aa4e-436fc2f6f604Jared<p>Hi,</p> <p>Are you asking if you need a RC filter on the reset pin?</p> <p>regards</p> <p>Jared&nbsp;</p><div style="clear:both;"></div>
