PIC16F785/HV785
9.1.2.2
Comparator C2 has one additional feature: its output
can be synchronized to the Timer1 clock input. Setting
C2SYNC (CM2CON1<0>) synchronizes the output of
Comparator 2 to the falling edge of the Timer1 clock
input (see Figure 9-2 and Register 9-3).
The CM2CON1 register also contains mirror copies of
both comparator outputs, MC1OUT and MC2OUT
(CM2CON1<7:6>). The ability to read both outputs
simultaneously from a single register eliminates the
timing skew of reading separate registers.

Obtaining the status of C1OUT or C2OUT
by reading CM2CON1 does not affect the
comparator interrupt mismatch registers.

bit 7
MC1OUT: Mirror Copy of C1OUT bit (CM1CON0<6>)
MC2OUT: Mirror Copy of C2OUT bit (CM2CON0<6>)
Unimplemented: Read as ‘0’
T1GSS: Timer1 Gate Source Select bit
1 = Timer1 gate source is RA4/AN3/T1G/OSC2/CLKOUT
0 = Timer1 gate source is SYNCC2OUT.
C2SYNC: C2 Output Synchronous Mode bit
1 = C2 output is synchronous to falling edge of TMR1 clock
0 = C2 output is asynchronous
