Note 1. The flag can only be set to 0 by writing 0 after reading 1.
CnFLAG Flag (Comparator Channel n Output Detection Flag) (n = 0 to 2)
This flag indicates whether each comparator output is detected or not detected.
[Setting condition]
 A change from low level to high level in the comparator output is detected.
- When the comparator is set to non-inverted output, the input voltage changes from lower to higher than the
reference voltage
- When the comparator is set to inverted output, the input voltage changes from higher to lower than the reference
voltage
[Clearing condition]
 By writing 0 to the CnFLAG flag after reading CnFLAG = 1
