11.3 Watch Dog Timer

11.3.1 Overview

The watchdog timer rapidly detects the CPU malfunction such as endless looping caused by noise or the like, and

resumes the CPU to the normal state. The watchdog timer signal for detecting malfunction can be selected either a

reset CPU or an interrupt request. When the watchdog timer is not being used for malfunction detection, it can be used

as a timer to generate an interrupt at fixed intervals. It is possible to use free running 8-bit timer mode (WDTRSON=’0’)

or watch dog timer mode (WDTRSON=’1’) as setting WDTMR[6] bit. If writing WDTMR[5] to ‘1’, WDT counter value is

cleared and counts up. After 1 machine cycle, this bit has ‘0’ automatically. The watchdog timer consists of 8-bit binary

counter and the watchdog timer data register. When the value of 8-bit binary counter is equal to the 8 bits of WDTR,

the interrupt request flag is generated. This can be used as Watchdog timer interrupt or reset the CPU in accordance

with the bit WDTRSON.

The clock source of Watch Dog Timer is BIT overflow output. The interval of watchdog timer interrupt is decided by BIT

overflow period and WDTR set value. The equation is as below

WDT Interrupt Interval = (BIT Interrupt Interval) X (WDTR Value+1)
