12.3  Operation

Operations when the WDT is used as a watchdog timer and as an interval timer are described
below.

12.3.1  Watchdog Timer Operation

Figure 12-4 illustrates watchdog timer operation. To use the WDT as a watchdog timer, set the
WT/

IT

and TME bits to 1 in TCSR. Software must prevent TCNT overflow by rewriting the

TCNT value (normally by writing H'00) before overflow occurs. If TCNT fails to be rewritten and
overflows due to a system crash etc., the chip is internally reset for a duration of 518 states.

The watchdog reset signal can be externally output from the 

RESO

pin to reset external system

devices. The reset signal is output externally for 132 states. External output can be enabled or
disabled by the RSTOE bit in RSTCSR.

A watchdog reset has the same vector as a reset generated by input at the 

RES

pin. Software can

distinguish a 

RES

reset from a watchdog reset by checking the WRST bit in RSTCSR.

If a 

RES

reset and a watchdog reset occur simultaneously, the 

RES

reset takes priority.
