The COP will continue to operate normally during wait mode. The
software should pull the device out of wait mode periodically and reset
the COP by writing to the COPC bit to prevent a COP reset.
Stop mode disables the oscillator circuit and thereby turns the clock off
for the entire device. The COP counter will be reset when stop mode is
entered. If a reset is used to exit stop mode, the COP counter will be
reset after the 4064 cycles of delay after stop mode. If an interrupt is
used to exit stop mode, the COP counter will not be reset after the
4064-cycle delay and will have that many cycles already counted when
control is returned to the program.
The COP is disabled by hardware during self-check mode.
