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

The WDT features are described below.
• Selectable from eleven counter input clocks
• Watchdog timer mode
• Interval timer mode
• Use of module standby mode enables this module to be placed in standby mode independently
