When the WCRR overflows, an active-low reset pulse is generated to the PRCM module. This pulse is one prescaled timer clock cycle wide and occurs at the same time as the timer counter overflow.
After reset generation, the counter is automatically reloaded with the value stored in the WLDR and the prescaler is reset (the prescaler ratio remains unchanged). When the reset pulse output is generated, the timer counter begins incrementing again.
Figure 24-21 shows a general functional view of the watchdog timers.
