https://devzone.nordicsemi.com/f/nordic-q-a/59382/programming-interface-for-segger-w-segger-jlinkHello- I am developing my first project with the nRF9160. It is on a custom board. I am planning on using Segger studio with the Segger JLink programmer with the 10-Pin connector. Could I get a sanity check that the following is how I should set upen-USTelligent Community 13Mon, 23 Mar 2020 14:08:56 GMThttps://devzone.nordicsemi.com/thread/241164?ContentTypeID=1Mon, 23 Mar 2020 14:08:56 GMT137ad170-7792-4731-bb38-c0d22fbe4515:35099339-bfa1-4a65-b0a1-a2221fc6e774Jared<p>Hi,</p> <ol> <li>No. From the <a href="https://infocenter.nordicsemi.com/topic/ps_nrf9160/pmureset.html?cp=2_0_0_4_0_4_1#pin_reset">product specification</a>: <em>&quot;nRESET pin has an always-on internal pull-up resistor connected to nRF9160 internal voltage typically of 2.2 V level.
