dwm_int_cfg_set
It enables/disables the setting ofa a dedicated GPIO pin in case of an event. Also, interrupts/events are communicated to the user by setting GPIO pin CORE_INT1. Users can use the pin as a source of an external interrupt. The interrupt can be processed by reading the status (dwm_status_get) and reacting to the new status accordingly. The status is cleared when read. This call is available only on UART/SPI interfaces. Normally, this call writes to internal flash when setting a new value. Hence, it should not be used frequently and can take hundreds of milliseconds in the worst case!

void dwm_int_cfg_set(void)
- Parameters
input – spi_data_ready, loc_ready, bh_status_changed, bh_data_ready, bh_initialized_changed, uwb_scan_ready, usr_data_ready, :param uwbmac_joined_changed
spi_data_ready – ‘0’ | ‘1’ (new SPI data generates interrupt on dedicated GPIO pin , 0=disable, 1=enable)
loc_ready – ‘0’ | ‘1’ (interrupt is generated when location data are ready, 0=disable, 1=enable)
bh_status_changed – ‘0’ | ‘1’ (UWBMAC status changed, 0=disable, 1=enable)
bh_data_ready – ‘0’ | ‘1’ (UWBMAC backhaul data ready, 0=disable, 1=enable)
bh_initialized_changed – ‘0’ | ‘1’ (UWBMAC route configured, 0=disable, 1=enable)
uwb_scan_ready – ‘0’ | ‘1’ (UWB scan result is available)
usr_data_ready – ‘0’ | ‘1’ (user data received over UWBMAC)
uwbmac_joined_changed – ‘0’ | ‘1’ (UWBMAC joined, 0=disable, 1=enable)
usr_data_sent – ‘0’ | ‘1’ (user data TX completed over UWBMAC)
output – err_code

Not available in the on-module user application. Available only on external interfaces (SPI, UART)
