8.8
There are three additional comparator features:
• Timer1 count enable (gate)
• Synchronizing output with Timer1
• Simultaneous read of comparator outputs
8.8.1
This feature can be used to time the duration or interval
of analog events. Clearing the T1GSS bit of the
CM2CON1 register will enable Timer1 to increment
based on the output of Comparator C2. This requires
that Timer1 is on and gating is enabled. See
Section 6.0 “Timer1 Module with Gate Control” for
details.
It is recommended to synchronize the comparator with
Timer1 by setting the C2SYNC bit when the comparator
is used as the Timer1 gate source. This ensures Timer1
does not miss an increment if the comparator changes
during an increment.

8.8.2
The Comparator C2 output can be synchronized with
Timer1 by setting the C2SYNC bit of the CM2CON1
register. When enabled, the C2 output is latched on the
falling edge of the Timer1 clock source. If a prescaler is
used with Timer1, the comparator output is latched after
the prescaling function. To prevent a race condition, the
comparator output is latched on the falling edge of the
Timer1 clock source and Timer1 increments on the
rising edge of its clock source. See the Comparator
Block Diagram (Figure 8-3) and the Timer1 Block
Diagram (Figure 6-1) for more information.
8.8.3
The MC1OUT and MC2OUT bits of the CM2CON1
register are mirror copies of both comparator outputs.
The ability to read both outputs simultaneously from a
single register eliminates the timing skew of reading
separate registers.
