C2OUT: Comparator 2 Output bit
When C2INV = 0:
1 = C2 VIN+ > C2 VIN-
0 = C2 VIN+ < C2 VIN-
When C2INV = 1:
0 = C2 VIN+ > C2 VIN-
1 = C2 VIN+ < C2 VIN-
bit 6
C1OUT: Comparator 1 Output bit
When C1INV = 0:
1 = C1 VIN+ > C1 VIN-
0 = C1 VIN+ < C1 VIN-
When C1INV = 1:
0 = C1 VIN+ > C1 VIN-
1 = C1 VIN+ < C1 VIN-
bit 5
C2INV: Comparator 2 Output Inversion bit
1 = C2 output inverted
0 = C2 output not inverted
bit 4
C1INV: Comparator 1 Output Inversion bit
1 = C1 output inverted
0 = C1 output not inverted
bit 3
C2NEG: Comparator 2 Negative Input Configure bit
1 = Input is connected to VIN+
0 = Input is connected to VIN-
See Figure 21-1 for the comparator modes.
bit 2
C2POS: Comparator 2 Positive Input Configure bit
1 = Input is connected to VIN+
0 = Input is connected to CVREF
See Figure 21-1 for the comparator modes.
bit 1
C1NEG: Comparator 1 Negative Input Configure bit
1 = Input is connected to VIN+
0 = Input is connected to VIN-
See Figure 21-1 for the comparator modes.
bit 0
C1POS: Comparator 1 Positive Input Configure bit
1 = Input is connected to VIN+
0 = Input is connected to CVREF
See Figure 21-1 for the comparator modes.
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
x = Bit is unknown
