https://devzone.nordicsemi.com/f/nordic-q-a/48743/nrf52840-pin-reset-pull-upPlease confirm the following is correct for nRF52840 (per PS v1.1) 1. The firmware doesn&#39;t have to enable internal pull-up when the pin reset is configured (it&#39;s done automatically by nRF52840) 2. There is no need for off-chip pull-up resistor.
