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.
When monitor mode is entered with V
disabled as long as V
monitor mode is entered by having blank reset vectors and not having
V
occurs.
The WAIT and STOP instructions put the MCU in low
power-consumption standby modes.
