According to CFEDGE, this register acts differently. If CFEDGE is level
type, comparator flag polarity has level value. If CFEDGE is edge type,
comparator flag polarity has edge value.
CFPOLA4
Determine the polarity of Comparator4 flag
0
When High level or rising edge, flag occurs(default)
1
When Low level or falling edge, flag occurs
CFPOLA3
Determine the polarity of Comparator3 flag
0
When High level or rising edge, flag occurs(default)
1
When Low level or falling edge, flag occurs
CFPOLA2
Determine the polarity of Comparator2 flag
0
When High level or rising edge, flag occurs(default)
1
When Low level or falling edge, flag occurs
CFPOLA1
Determine the polarity of Comparator1 flag
0
When High level or rising edge, flag occurs(default)

If CFBOTHx is written to ‘1’, the corresponding comparator flag is
enabled by both edges(no level).
And CFEDGE and CFPOLA register value are ignored.
