Computer Operating Properly (COP)
12.8.2 STOP Mode
STOP mode turns off the CGMXCLK input to the COP and clears the
COP prescaler. The COP should be serviced immediately before
entering or after exiting STOP mode to ensure a full COP timeout period
after entering or exiting STOP mode.
The STOP bit in the mask option register (MOR) enables the STOP
instruction. To prevent inadvertently turning off the COP with a STOP
instruction, the STOP instruction should be disabled by programming the
STOP bit to ‘0’.
12.9 COP Module During Break Interrupts
The COP is disabled during a break interrupt when V_HI is present on the
RST pin.
