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
IRQ1 pin or on the RST pin.
The WAIT and STOP instructions put the MCU in low-power
consumption standby modes.
The COP continues to operate during wait mode. To prevent a COP
reset during wait mode, periodically clear the COP counter in a CPU
interrupt routine.
