The watchdog timer consists of the binary counters that are arranged in 26 stages and work using the

The output pin of the watchdog timer can reset the peripherals by outputting “0” caused by an
overflow. The output is set to “1”if the watchdog timer is cleared (if the clear code 4EH is written to the
WDCR register). The
WDCR register.
(Note)
When an overflow occurs, resetting the chip itself is an option to choose. If the chip is reset, a reset is
affected for a 32-state time, as shown in Fig. 16-3. If this reset is affected, the clock f
gear generates by dividing the clock f
