REGISTER 20-1: CMxCON: COMPARATOR x CONTROL REGISTERS (CONTINUED)
bit 4
bit 3-2
bit 1-0
CREF: Comparator Reference Select bits (non-inverting input)
1 = Non-inverting input connects to the internal CVREF voltage
0 = Non-inverting input connects to the CxINA pin
Unimplemented: Read as ‘0’
CCH<1:0>: Comparator Channel Select bits
11 = Inverting input of the comparator connects to VBG/2
10 = Inverting input of the comparator connects to CxIND pin(1)
01 = Inverting input of the comparator connects to CxINC pin(1)
00 = Inverting input of the comparator connects to CxINB pin
Note 1: Unimplemented on 14-pin (PIC24FXXKL100/200) devices.

CMIDL: Comparator Stop in Idle Mode bit
1 = Discontinue operation of all comparators when device enters Idle mode
0 = Continue operation of all enabled comparators in Idle mode
Unimplemented: Read as ‘0’
C2EVT: Comparator 2 Event Status bit (read-only)(1)
Shows the current event status of Comparator 2 (CM2CON<9>).
C1EVT: Comparator 1 Event Status bit (read-only)
Shows the current event status of Comparator 1 (CM1CON<9>).
Unimplemented: Read as ‘0’
C2OUT: Comparator 2 Output Status bit (read-only)(1)
Shows the current output of Comparator 2 (CM2CON<8>).
C1OUT: Comparator 1 Output Status bit (read-only)
Shows the current output of Comparator 1 (CM1CON<8>).
Note 1: These bits are unimplemented on PIC24FXXKL10X/20X devices.
