IRQ Handler for Radio - not entered

[Erlend]

I'm trying to enable interrupt for radio events.

I have this code in main:

bsp_board_leds_init();
(...)
NRF_RADIO->INTENSET = 1 << RADIO_INTENSET_READY_Pos;
NRF_RADIO->TASKS_TXEN = 1;
while(1) {}

And I have defined this function:

void RADIO_IRQHandler(void) {
  bsp_board_led_invert(LED_2);
  int a = 0;
}

The a variable was just for setting a breakpoint before I added the other line. Setting a breakpoint on either line: execution never stops there, and the GPIO line isn't toggled.

Hi,

Have you enabled the interrupt in the NVIC ?

NVIC_ClearPendingIRQ(RADIO_IRQn);
NVIC_EnableIRQ(RADIO_IRQn);

Note that you are setting the READY bit in the INTENSET register, this will enable interrupt for READY EVENT, which is when the RADIO has ramped up and is ready to be started.

Indeed missed that. But where would I find information that I have to enable the IRQ line in the NVIC - and on how to do it? I don't find anything about it in the reference manual.
