NRF_ERROR_NO_MEM on nrfx_gpiote_in_init

[nrbrook]

When attempting to initiate GPIOTE pins, I get an NRF_ERROR_NO_MEM on the 5th pin. I saw reference to there being a maximum of 4 high accuracy channels but I am attempting to initiate with low accuracy.

// button inputs
nrfx_gpiote_in_config_t config = NRFX_GPIOTE_CONFIG_IN_SENSE_TOGGLE(false);
config.pull = NRF_GPIO_PIN_PULLDOWN;

for(int i = 0; i < ATPALDigitalInputMaxNumberInputs; i++) {
    NRF_LOG_INFO("pin %d", m_hardwareCustomisation->digital.inputs.buttonMapping[i]);
    err_code = nrfx_gpiote_in_init(m_hardwareCustomisation->digital.inputs.buttonMapping[i], &config, gpiote_event_handler);
    APP_ERROR_CHECK(err_code);
}

Hi,

Increase GPIOTE_CONFIG_NUM_OF_LOW_POWER_EVENTS and/or NRFX_GPIOTE_CONFIG_NUM_OF_LOW_POWER_EVENTS in sdk_config.h to the number of low accuracy GPIOTE pins you are using.
