https://devzone.nordicsemi.com/f/nordic-q-a/15734/nrf52-gpio-latch-registerHi I want to use nrf52 LATCH register. I can see the correct bit set in the register, but I am unable to clear this bit. I have tried NRF_P0-&gt;LATCH =0xFFFFFFFF; for my understanding this should clear all the bits in the LATCH register.
