Oh dear, I should have known that - all good now. Thanks Vidar!

Hi,

You will need to call NVIC_EnableIRQ(GPIOTE_IRQn) to enable the interrupt in the NVIC as well. Also, remember to clear the GPIOTE event from your interrupt handler. Otherwise the interrupt will be triggered again as soon as you exit the handler.

//Clearing IN event

NRF_GPIOTE->EVENTS_IN[CHANNEL_NUM] = 0;
