To set the interrupt, follow the procedure shown in figure 18.3 or 18.4.

Set the CME bit. Wait a conversion time for the comparator stabilized.
Read the CDR bit.
Set the CMIE bit.
Read the CDR bit. At this time, the CDR bit is latched in the internal latch for the comparator
and the internal interrupt enable signal is asserted.
As the relationship between the voltage on the COMP pin and reference voltage is changed,
a difference occurs between the output level of the internal latch and the CDR bit. Then an
interrupt is generated.
Clear the CMF bit in the interrupt handler. When reading the CMF bit for clearing it, the CDR bit is
also read since those bits are in the same register. Therefore, the output of the internal latch is
updated. Go to step [5] to continue use of the interrupt.
Clear the CMIE bit to clear the interrupt setting and clear the CME bit to stop the comparator.
Clearing the CMIE bit negates the internal interrupt enable signal.
The interrupt flag may be set depending on the internal states of the comparator, pin states, the
timing of setting the internal interrupt enable signal shown in step [4], and the timing of the CDR bit
latched. To avoid this, execute steps [2] to [4] continuously or ensure that the CMF bit is cleared
using the I bit in CCR as shown in figure 18.4.
