Section 12 Watchdog Timer

The watchdog timer(WDT) is an 8-bit timer that can generate an internal reset signal for this LSI
if a system crash prevents the CPU from writing to the timer counter, thus allowing it to overflow.

The block diagram of the WDT is shown in figure 12-1.

oscillator can be selected as the timer-counter clock. When the internal oscillator is selected, it
can operate as the watchdog timer in any operating mode, except in standby mode.

•

Reset signal generated on counter overflow

An overflow period of 1 to 256 times the selected clock can be set.
