PIC16C781/782
12.1.2.2
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 Timer 1’s clock input
(see Figure 12-1 and Register 12-3).
REGISTER 12-3:
DS41171A-page 94
bit 7
bit 6
bit 5-1
bit 0
Control Register CM2CON1
COMPARATOR C2 CONTROL REGISTER1 (CM2CON1: 11Bh)
MC1OUT: Mirror Copy of C1OUT (CM1CON0<6>)
MC2OUT: Mirror Copy of C2OUT (CM2CON0<6>)
Unimplemented: Read as ’0’
C2SYNC: C2 Output Synchronous Mode bit
1 = C2 output is synchronous to falling edge of TMR1 clock
0 = C2 output is asynchronous
bit 7

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.
