Computer Operating Properly Module (COP)
5.8.2 Stop Mode
Stop mode holds the 12-bit prescaler counter in reset until after stop mode is exited. 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 has the STOP instruction
disabled, execution of a STOP instruction results in an illegal opcode reset.
