C2ON: Comparator C2 Enable bit
1 = C2 Comparator is enabled
0 = C2 Comparator is disabled
C2OUT: Comparator C2 Output bit
If C2POL = 1 (inverted polarity):
If C2POL = 0 (non-inverted polarity):
C2OE: Comparator C2 Output Enable bit
1 = C2OUT is present on RB7/C2/PSMC1B/T1G
0 = C2OUT is internal only
C2POL: Comparator C2 Output Polarity Select bit
1 = C2OUT logic is inverted
0 = C2OUT logic is not inverted
C2SP: Comparator C2 Speed Select bit
1 = C2 operates in normal speed mode
0 = C2 operates in low power, slow speed mode.
C2R: Comparator C2 Reference Select bits (non-inverting input)
1 = C2VP connects to V
0 = C2VP connects to V
C2CH<1:0>: Comparator C2 Channel Select bits
00 = C2VN of C2 connects to AN4
01 = C2VN of C2 connects to AN5
10 = C2VN of C2 connects to AN6
11 = C2VN of C2 connects to AN7
Note 1: C2OUT will only drive RB7/C2/PSMC1B/T1G if:
