### Testing procedure
Testing procedure has to be done preferably without pull resistors (so no PR #11132).
Either touch the DIO3 in the board with a jumper wire or try to set it to high and low to trigger the interrupt. The application will crash without this PR.

Alternatively, call netdev->event_callback with NETDEV_EVENT_CAD_DONE. It will have the same effect.
