https://devzone.nordicsemi.com/f/nordic-q-a/119948/nrf52832-p0-20-high-on-powerupHello, We&#39;re developing a project on a custom board based on nRF52832 and noticed that P0.20 is high on powerup, even with no firmware.

All pins are disconnected, i.e floating before they are defined. If you measure a high level, something else is pulling this high</p><div style="clear:both;"></div>
