An error detected by the watchdog often indicates that
a problem has occurred in the μP code execution. This
could be a stalled instruction or a loop from which the
processor cannot free itself. If the μP will still respond
to a nonmaskable input (NMI), the processor can be
redirected to the proper code sequence by connecting
the WDPO output to an NMI input. Internal RAM data
should not be lost, but it may have been contaminated
by the same error that caused the watchdog to time
out.
If the processor will not recognize NMI inputs, or if the
internal data is considered potentially corrupted when
a watchdog error occurs, the processor should be
restarted with a reset function. To obtain proper reset
timing characteristics, the WDPO output should be
connected to the MR input, and the RESET output
should drive the μP RESET input (Figure 10). The short
1ms WDPO pulse output will assert the manual reset
input and force the RESET output to assert for the full
reset timeout period (100ms min). All internal RAM data
is lost during the reset period, but the processor is
guaranteed to begin in the proper operating state.
