Computer Operating Properly (COP)
19.8.1 Wait Mode
19.8.2 Stop Mode
19.9 COP Module During Break Mode
Data Sheet
262
The COP remains active during wait mode. To prevent a COP reset
during wait mode, periodically clear the COP counter in a CPU interrupt
routine.
Stop mode turns off the OSCXCLK 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.
The COP is disabled during a break interrupt when V
the RST pin.
