Information
The watchdog functions of the requests 0x14 segment 0x02 and 0x53 use
the same watchdog timer. In other words, the watchdog timer is reset if ei-
ther request is called.
Information
To test if the watchdog is active, set a virtual input continuously to "1".
If this input becomes "0" after the set watchdog timeout has elapsed, then
the watchdog is active.
