Watchdog Timer
The Watchdog Timer represents one of the fail-safe mechanisms which have been
implemented to prevent the controller from malfunctioning for longer periods of time.
The Watchdog Timer is always enabled after a reset of the chip, and can be disabled
until the EINIT instruction has been executed (compatible mode), or it can be disabled
and enabled at any time by executing instructions DISWDT and ENWDT (enhanced
mode). Thus, the chip’s start-up procedure is always monitored. The software has to be
designed to restart the Watchdog Timer before it overflows. If, due to hardware or
software related failures, the software fails to do so, the Watchdog Timer overflows and
generates an internal hardware reset.
The Watchdog Timer is a 16-bit timer, clocked with the system clock divided by
2/4/128/256. The high byte of the Watchdog Timer register can be set to a prespecified
reload value (stored in WDTREL) in order to allow further variation of the monitored time
interval. Each time it is serviced by the application software, the high byte of the
Watchdog Timer is reloaded and the low byte is cleared. Thus, time intervals between
13
s and 419 ms can be monitored (@ 40 MHz).
The default Watchdog Timer interval after reset is 3.28 ms (@ 40 MHz).
