Technical Data
NOTE:
NOTE:
NOTE:
The STOP and WAIT instructions have these effects on the COP
watchdog.
The STOP instruction clears the COP watchdog counter and disables
the clock to the COP watchdog.
To prevent the STOP instruction from disabling the COP watchdog,
program the stop-to-wait conversion bit (SWAIT) in the mask option
register to logic 1.
Upon exit from stop mode by external reset:
Upon exit from stop mode by external interrupt:
Immediately after exiting stop mode by external interrupt, service the
COP to ensure a full COP timeout period.
The WAIT instruction has no effect on the COP watchdog.
To prevent a COP timeout during wait mode, exit wait mode periodically
to service the COP.
