            Selecting HFXO will still mostly use the HFINT but will switch to HFXO when requested (BLE, certain timers, etc...)

        description: >
            When enabled, hal_gpio will use GPIOTE PORT event instead of PIN
            events for interrupts. This mode may be less accurate (i.e. pulse
            length needs to be longer in order to be detected) but it reduces
            power consumption since it does not require HFCLK to be running.

            (It can only be enabled if it was not already disabled before).  If it was disabled
            MCU has to be erased (UICR and FLASH) to enable debugger again.
            If left to default, does not write APPROTECT. Debugger may be enabled if APPROTECT
            has already 0x5A value or for older revisions 0xFF.
