https://devzone.nordicsemi.com/f/nordic-q-a/33548/the-circuit-has-to-hang-with-fixed-currenthi all, I have an issue with hardware in the circuit, which is designed by my self. The PCB has designed a customized condition: I have erased full memory and measure current consumption, it is as 2.45mA Then I have connected load with pin p0en-USTelligent Community 13Fri, 20 Apr 2018 09:04:35 GMThttps://devzone.nordicsemi.com/thread/129110?ContentTypeID=1Fri, 20 Apr 2018 09:04:35 GMT137ad170-7792-4731-bb38-c0d22fbe4515:08498b12-5e54-4662-b036-d9e25724160aSigurd<p>Hi,</p> <p><br />It should generally be enough to add a 1k resistor on SWDCLK to prevent the nRF51 accidentally entering debug mode. You should not need a resistor on SWDIO. See <a href="https://devzone.nordicsemi.com/f/nordic-q-a/16530/issue-with-nrf51-unexpectedly-entering-debug-mode/">this post</a>.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/128927?ContentTypeID=1Thu, 19 Apr 2018 09:36:21 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3d7648d8-4d75-4bd2-9cd1-c03f0130702eSatheeshkumar<p>I have found the issue why it&#39;s hanging in 1.154mA. when I was short the pin, it is entering debug mode. can anyone help me to handle the debug interface in the circuit diagram?&nbsp;I have added a 12k resistor in SWDCLK pin with ground and added 10k resistor in SWDIO pin with VDD.&nbsp;This the debugging enable and disable&nbsp;circuit. whether is&nbsp;it correct or any other modification?</p> <p><img src="https://devzone.nordicsemi.com/resized-image/__size/320x240/__key/communityserver-discussions-components-files/4/pastedimage1524130358985v1.png" alt=" " /></p><div style="clear:both;"></div>
