Timed Sequences for Changing the Configuration of the Watchdog Timer
Safety Level 1
Safety Level 2
“Timed Sequences for Changing the Configuration of the Watchdog Timer” on page 45
details.
Table 8-1.
Figure 8-7.
The sequence for changing configuration differs slightly between the two safety levels. Separate
procedures are described for each level.
In this mode, the Watchdog Timer is initially disabled, but can be enabled by writing the WDE bit
to one without any restriction. A timed sequence is needed when disabling an enabled Watch-
dog Timer. To disable an enabled Watchdog Timer, the following procedure must be followed:
In this mode, the Watchdog Timer is always enabled, and the WDE bit will always read as one. A
timed sequence is needed when changing the Watchdog Time-out period. To change the
Watchdog Time-out, the following procedure must be followed:
