Fig. 4.2 Events related to internal restart triggers
Note:
In case the radio was restarted on the basis of the WD RESTART
trigger and the consequent boot process was interrupted by switching the
radio off (mains failure), the original restart event (e.g. 409 RX WD
RESTART) is logged in the event log.
