Address:
The COP control register is located at address $FFFF and overlaps the
reset vector. Writing any value to $FFFF clears the COP counter and
starts a new timeout period. Reading location $FFFF returns the low
byte of the reset vector.
The COP does not generate CPU interrupt requests.
The COP is disabled in monitor mode when V
pin or on the RST pin.
The WAIT and STOP instructions put the MCU in low power-
consumption standby modes.
The COP remains active in wait mode. To prevent a COP reset during
wait mode, periodically clear the COP counter in a CPU interrupt routine.
