Fail Save Mechanisms
The C515C offers two on-chip peripherals which monitor the program flow and ensure
an automatic “fail-safe” reaction for cases where the controller’s hardware fails or the
software hangs up:
A programmable watchdog timer (WDT) with variable time-out period from
512 microseconds up to approx. 1.1 seconds at 6 MHz.
An oscillator watchdog (OWD) which monitors the on-chip oscillator and forces the
microcontroller into reset state in case the on-chip oscillator fails; it also provides the
clock for a fast internal reset after power-on.
Programmable Watchdog Timer
The watchdog timer in the C515C is a 15-bit timer, which is incremented by a count rate
of
fOSC/12 up to fOSC/192. For programming of the watchdog timer overflow rate, the
upper 7 bit of the watchdog timer can be written. Figure 23 shows the block diagram of
the watchdog timer unit.

Block Diagram of the Programmable Watchdog Timer
The watchdog timer can be started by software (bit SWDT) or by hardware through pin
PE/SWD, but it cannot be stopped during active mode of the C515C. If the software fails
to refresh the running watchdog timer an internal reset will be initiated on watchdog timer
overflow. For refreshing of the watchdog timer the content of the SFR WDTREL is
transferred to the upper 7-bit of the watchdog timer. The refresh sequence consists of
