Run mode
If COP functionality is required, the individual bits of the associated rate select registers (COPCTL) have to be set to a
non-zero value. The COP is stopped if all rate select bits are zero.
Wait mode
If the respective enable bit (COPSWAI) is cleared, the COP will continue to run, else COP remains frozen.
Stop mode
If the respective enable bit (COPRSTP) is set, the COP will continue to run, else COP remains frozen.
