Low-Power Modes
Upon exit from stop mode by external reset:
• The counter begins counting from $0000.
• The counter is cleared again after the oscillator stabilization delay and begins counting from $0000
again.
Upon exit from stop mode by external interrupt:
• The counter begins counting from $0000.
• The counter is not cleared again after the oscillator stabilization delay and continues counting
throughout the oscillator stabilization delay.
NOTE
Immediately after exiting stop mode by external interrupt, service the COP
to ensure a full COP timeout period.
3.6.2 Wait Mode
The WAIT instruction has no effect on the COP watchdog.
NOTE
To prevent a COP timeout during wait mode, exit wait mode periodically to
service the COP.
