Computer Operating Properly Module (COP)
11.9.2 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 inadvertantly turning off the COP with a STOP instruciton, 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.
