Computer Operating Properly (COP) Module
5.7.2 Stop Mode
Stop mode turns off the COPCLK 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.
To prevent inadvertently turning off the COP with a STOP instruction, a configuration option is available
that disables the STOP instruction. When the STOP bit in the configuration register has the STOP
instruction is disabled, execution of a STOP instruction results in an illegal opcode reset.
5.8 COP Module During Break Mode
The COP is disabled during a break interrupt when V
is present on the RST pin.
