Fail Safe Mechanisms
The SAB-C502 offers enhanced fail safe mechanisms, which allow an automatic recovery from
software upset or hardware failure.
1) Watchdog Timer (15 bit, WDT)
2) Oscillator Watchdog (OWD)
1) Watchdog Timer (WDT)
The Watchdog Timer in the SAB-C502 is a 15-bit timer, which is incremented by a count rate of
either
f
CYCLE
/2 or
f
CYCLE
/32 (
f
CYCLE
=
f
OSC
/12). That is, the machine clock is divided by a series of
arrangement of two prescalers, a divide-by-two and a divide-by-16 prescaler. The latter is enabled
by setting bit WDTREL.7.
