Setting Up a Watchdog Timer Interrupt

The watchdog timer interrupt is

provided for detecting and handling

racing. Normal operation is not

guaranteed if the program returns

after a watchdog interrupt. For

actions requiring returns, use a

timer interrupt.

In this example, a watchdog timer reset occurs. The watchdog timer starts

running after a reset, when the NWDEN flag in the CPU mode register (CPUM)
is enabled (set to 0). When the watchdog timer overflows, a nonmaskable

interrupt occurs. This means that the watchdog timer must be cleared in the main
program.

Enabling watchdog timer interrupts

Enable interrupts by writing a 1 to the interrupt enable flag (IE) in the PSW
and setting the interrupt masking level (IM[2:0]) to 7 (b’111’).

If WDM[1:0] = 00, a watchdog
interrupt occurs when the watch-

dog timer counts 2

cycles

(5.4613 ms at 4-MHz f

/12-

). The WDM set-

tings have the following mean-

ings:

00:

(5.46 ms)

01:

(1.33 µs)

10:

(0.34 ms)

11:

(1.37 ms)

Activate the watchdog timer by clearing the NWDEN bit of the CPUM regis-
ter. Set the time limit for the racing detection function in the WDM[1:0]

field.

■

Clearing the watchdog timer

The main program normally
clears the watchdog timer prior

to a watchdog interrupt.

Set the NWDEN bit in CPUM to 1, then immediately reset it to 0. The
watchdog timer clears to 0 when NWDEN is 1.
