13.7
If ECCP modules are configured to use Timer1 and to
generate a Special Event Trigger in Compare mode
(CCPxM<3:0> = 1011), this signal will reset Timer1. The
trigger from ECCP2 will also start an A/D conversion, if
the A/D module is enabled. (For more information, see
Section 19.3.4 “Special Event
To take advantage of this feature, the module must be
configured as either a timer or a synchronous counter.
When used this way, the CCPRxH:CCPRxL register
pair effectively becomes a Period register for Timer1.
If Timer1 is running in Asynchronous Counter mode,
this Reset operation may not work.
In the event that a write to Timer1 coincides with a
Special Event Trigger, the write operation will take
precedence.

Timer1 can be configured to count freely or the count can
be enabled and disabled using the Timer1 gate circuitry.
This is also referred to as Timer1 gate count enable.
Timer1 gate can also be driven by multiple selectable
sources.

The Timer1 Gate Enable mode is enabled by setting
the TMR1GE bit of the T1GCON register. The polarity
of the Timer1 Gate Enable mode is configured using
the T1GPOL bit (T1GCON<6>).
When Timer1 Gate Enable mode is enabled, Timer1
will increment on the rising edge of the Timer1 clock
source. When Timer1 Gate Enable mode is disabled,
no incrementing will occur and Timer1 will hold the
current count. See

TIMER1 GATE COUNT ENABLE
The CCP and ECCP modules use Timers,
1 through 8, for some modes. The assign-
ment of a particular timer to a CCP/ECCP
module is determined by the Timer to CCP
enable bits in the CCPTMRSx registers.
