8.8
This feature can be used to time the duration or interval
of analog events. Clearing the T1GSS bit of the
CMCON1 register will enable Timer1 to increment
based on the output of the comparator. 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 CMSYNC bit when the compara-
tor is used as the Timer1 gate source. This ensures
Timer1 does not miss an increment if the comparator
changes during an increment.

The comparator output can be synchronized with
Timer1 by setting the CMSYNC bit of the CMCON1
register. When enabled, the comparator 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.
