Computer Operating Properly (COP)
13.7.1 Wait Mode
The COP continues to operate during wait mode. To prevent a COP reset during wait mode, periodically
clear the COP counter in a CPU interrupt routine.
13.7.2 Stop Mode
Stop mode turns off the 2OSCOUT input to the COP and clears the SIM counter. Service the COP
immediately before entering or after exiting stop mode to ensure a full COP timeout period after entering
or exiting stop mode.
13.8 COP Module During Break Mode
The COP is disabled during a break interrupt when V
is present on the RST pin.
