3.14
The System Timer consists of a programmable prescaler and two concatenated timers
(10 bits and 6 bits). Both timers can generate interrupt requests. The clock source can
be selected and the timers can also run during power reduction modes.
Therefore, the System Timer enables the software to maintain the current time for
scheduling functions or for the implementation of a clock.
3.15
The Watchdog Timer is 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 an application reset of the chip. It can be
disabled and enabled at any time by executing the instructions DISWDT and ENWDT
respectively. The software has to service the Watchdog Timer before it overflows. If this
is not the case because of a hardware or software failure, the Watchdog Timer
overflows, generating a prewarning interrupt and then a reset request.
The Watchdog Timer is a 16-bit timer clocked with the system clock divided by 16,384
or 256. The Watchdog Timer register is 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 Watchdog Timer is reloaded and the
prescaler is cleared.
Time intervals between 3.2 μs and 13.4 s can be monitored (@ 80 MHz).
The default Watchdog Timer interval after power-up is 6.5 ms (@ 10 MHz).
