Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared

CON: Comparator Enable bit
1 = Comparator is enabled
0 = Comparator is disabled
COE: Comparator Output Enable bit
1 = Comparator output is present on the CxOUT pin
0 = Comparator output is internal only
CPOL: Comparator Output Polarity Select bit
1 = Comparator output is inverted
0 = Comparator output is not inverted
CLPWR: Comparator Low-Power Mode Select bit
1 = Comparator operates in Low-Power mode
0 = Comparator does not operate in Low-Power mode
Unimplemented: Read as ‘0’
CEVT: Comparator Event bit
1 = Comparator event, defined by EVPOL<1:0>, has occurred; subsequent Triggers and interrupts are
disabled until the bit is cleared
0 = Comparator event has not occurred
COUT: Comparator Output bit
When CPOL = 0:
1 = VIN+ > VIN-
0 = VIN+ < VIN-
When CPOL = 1:
1 = VIN+ < VIN-
0 = VIN+ > VIN-
EVPOL<1:0>: Trigger/Event/Interrupt Polarity Select bits
11 = Trigger/event/interrupt is generated on any change of the comparator output (while CEVT = 0)
10 = Trigger/event/interrupt is generated on the transition of the comparator output:
If CPOL = 0 (non-inverted polarity):
High-to-low transition only.
If CPOL = 1 (inverted polarity):
Low-to-high transition only.
01 = Trigger/event/interrupt is generated on the transition of the comparator output
If CPOL = 0 (non-inverted polarity):
Low-to-high transition only.
If CPOL = 1 (inverted polarity):
High-to-low transition only.
00 = Trigger/event/interrupt generation is disabled
Unimplemented: Read as ‘0’
