The watchdog timer (WDT) is an 8-bit timer that outputs an overflow signal (WDTOVF) if a
system crash prevents the CPU from writing to the timer counter, thus allowing it to overflow. At
the same time, the WDT can also generate an internal reset signal.
When this watchdog function is not needed, the WDT can be used as an interval timer. In interval
timer operation, an interval timer interrupt is generated each time the counter overflows.
Figure 18.1 shows a block diagram of the WDT.

• Selectable from eight counter input clocks
• Switchable between watchdog timer mode and interval timer mode
⎯ In watchdog timer mode
⎯ In interval timer mode
If the counter overflows, the WDT outputs WDTOVF. It is possible to select whether or
not the entire LSI is reset at the same time.
If the counter overflows, the WDT generates an interval timer interrupt (WOVI).
