Computer Operating Properly Module (COP)
11.8.2 Stop Mode
Stop mode turns off the CGMXCLK input to the COP and clears the COP
prescaler. Service the COP immediately before entering or after exiting
stop mode to ensure a full COP timeout period after entering or exiting
stop mode.
The STOP bit (see Section 9. Configuration Register (CONFIG))
enables the STOP instruction. To prevent inadvertently turning off the
COP with a STOP instruction, disable the STOP instruction by clearing
the STOP bit.
11.9 COP Module During Break Interrupts
The COP is disabled during a break interrupt when V_HI is present on the
RST pin.
