Wortlaut
7.4 Watchdog Handling
The handling of watchdogs is an important feature of the Watchdog Manager module. It prevents the ECU from resets by expired hardware watchdog instances while program execution is running properly. Usually hardware watchdogs have their own timing constraints and the trigger for each watchdog instance must be performed cyclically within a maximum time span or within a defined time window according to the timing constraints of the corresponding watchdog instance. If the trigger does not occur, the corresponding hardware watchdog instance will cause a reset. The actual timing of watchdog triggering is encapsulated in the Watchdog Driver. The Watchdog Manager only sets via the Watchdog Interface a triggering condition that instructs the Watchdog Driver to continue triggering.
