Compare Mode
In Compare mode, the 16-bit CCPR1 register value is
constantly compared against the TMR1 register pair
value. When a match occurs, the CCP1 module may:
Toggle the CCP1 output.
Set the CCP1 output.
Clear the CCP1 output.
Generate a Special Event Trigger.
Generate a Software Interrupt.
The action on the pin is based on the value of the
CCP1M<3:0> control bits of the CCP1CON register.
All Compare modes can generate an interrupt.

11.2.1
CCP1 PIN CONFIGURATION
The user must configure the CCP1 pin as an output by
clearing the associated TRIS bit.
11.2.2
TIMER1 MODE SELECTION
In Compare mode, Timer1 must be running in either
Timer mode or Synchronized Counter mode. The
compare operation may not work in Asynchronous
Counter mode.
11.2.3
SOFTWARE INTERRUPT MODE
When Generate Software Interrupt mode is chosen
(CCP1M<3:0> = 1010), the CCP1 module does not
assert control of the CCP1 pin (see the CCP1CON
register).
11.2.4
SPECIAL EVENT TRIGGER
When
Special
Event
Trigger
mode
is
chosen
(CCP1M<3:0> = 1011), the CCP1 module does the
following:
Resets Timer1
Starts an ADC conversion if ADC is enabled
The CCP1 module does not assert control of the CCP1
pin in this mode (see the CCP1CON register).
The Special Event Trigger output of the CCP occurs
immediately upon a match between the TMR1H,
TMR1L register pair and the CCPR1H, CCPR1L
register pair. The TMR1H, TMR1L register pair is not
reset until the next rising edge of the Timer1 clock. This
allows
the
CCPR1H,
CCPR1L
register
pair
to
effectively provide a 16-bit programmable period
register for Timer1.
Note:
Clearing the CCP1CON register will force
the CCP1 compare output latch to the
default low level. This is not the GPIO I/O
data latch.

Note 1: The Special Event Trigger from the CCP
module does not set interrupt flag bit
TMRxIF of the PIR1 register.
2: Removing
the
match
condition
by
changing the contents of the CCPR1H
and CCPR1L register pair, between the
clock edge that generates the Special
Event Trigger and the clock edge that
generates the Timer1 Reset, will preclude
the Reset from occurring.
