18.4.1
The operation sequence of a comparator is as follows:
1. When using VCref, the pins to be used are enabled by the corresponding port mode registers.
2. Select the reference voltage (CMR setting: internal power supply or VCref).
3. Set the comparator enable bit (CME).
4. After setting CME, wait for the conversion time (see section 21, Electrical Characteristics) so
5. Read from CDR.
6. After reading the CMF flag, write 0 to it (reading the CMF flag can be performed
7. If an interrupt is to be generated, set the comparator interrupt enable bit (CMIE).
Note: Steps 2 and 3 can be done simultaneously by writing to the entire register.
