low power input interrupt

[Dhaval Dalvadi]

Hi

I am using gpio for input interrupt as below

nrf_drv_gpiote_in_config_t in_config = GPIOTE_CONFIG_IN_SENSE_HITOLO(true);
in_config.pull = NRF_GPIO_PIN_PULLUP;

err_code = nrf_drv_gpiote_in_init(PIN_IN, &in_config, in_pin_handler);
APP_ERROR_CHECK(err_code);

nrf_drv_gpiote_in_event_enable(PIN_IN, true);

it is working fine but consume more power. if I do not use that then power consumption reduce to 8ua to 9ua is there any other low power interrupt enable method?

I have read about use the PORT event to trigger a pin interrupt without increasing the current consumption. But don't know how to use that.is there any example that have used PORT event to trigger a pin interrupt?

Thanks

May i use it for detect long press of button? i mean when button press i will start app_timer for 10sec and after that i will check that it pressed or not. Beacause after changing to port event it's not working on long press
