How to program the Watchdog timeout
Figure 31
Watchdog Counter (CNT) and the resulting timeout duration in milliseconds. This can be
used for a quick calculation without taking the timing variations into account. If more
precision is needed, use the formulae in
When writing to the WDGCR register, always write 1 in the T6 bit to avoid generating an
immediate reset.
