The COP counter is a free-running 6-bit counter preceded by a 12-bit
prescaler counter. If not cleared by software, the COP counter overflows
and generates an asynchronous reset after 2
OSCXCLK cycles, depending on the state of the COP rate select bit,
COPRS, in configuration register 1. With a 2
overflow option, a 24MHz crystal gives a COP timeout period of
10.922ms. Writing any value to location $FFFF before an overflow
occurs prevents a COP reset by clearing the COP counter and stages
12 through 5 of the prescaler.
Service the COP immediately after reset and before entering or after
exiting stop mode to guarantee the maximum time before the first COP
counter overflow.
