6. Watchdog Timer (WDT)

6.2 Watchdog Timer Control

TMP86PM29BUG

6.2

Watchdog Timer Control

The watchdog timer is controlled by the watchdog timer control registers (WDTCR1 and WDTCR2). The watch-

dog timer is automatically enabled after the reset release.

6.2.1

Malfunction Detection Methods Using the Watchdog Timer

The CPU malfunction is detected, as shown below.

1. Set the detection time, select the output, and clear the binary counter.

2. Clear the binary counter repeatedly within the specified detection time.

If the CPU malfunctions such as endless loops or the deadlock conditions occur for some reason, the watch-

dog timer output is activated by the binary-counter overflow unless the binary counters are cleared. When
WDTCR1<WDTOUT> is set to “1” at this time, the reset request is generated and the

RESET

pin outputs a

low-level signal, then internal hardware is initialized. When WDTCR1<WDTOUT> is set to “0”, a watchdog
timer interrupt (INTWDT) is generated.

The watchdog timer temporarily stops counting in the STOP mode including the warm-up or IDLE/SLEEP

mode, and automatically restarts (continues counting) when the STOP/IDLE/SLEEP mode is inactivated.

Note:The watchdog timer consists of an internal divider and a two-stage binary counter. When the clear code 4EH

is written, only the binary counter is cleared, but not the internal divider. The minimum binary-counter overflow
time, that depends on the timing at which the clear code (4EH) is written to the WDTCR2 register, may be 3/
4 of the time set in WDTCR1<WDTT>. Therefore, write the clear code using a cycle shorter than 3/4 of the
time set to WDTCR1<WDTT>.
