15.2
In Compare mode, the 16-bit CCPRx register value is
constantly compared against the TMR1 register pair
value. When a match occurs, the CCPx module may:
• Toggle the CCPx output
• Set the CCPx output
• Clear the CCPx output
• Generate a Special Event Trigger
• Generate a Software Interrupt
The action on the pin is based on the value of the
CCPxM<3:0> control bits of the CCPxCON register.
All Compare modes can generate an interrupt.

The user must configure the CCPx pin as an output by
clearing the associated TRIS bit.
Either RC1 or RB3 can be selected as the CCP2 pin.
Refer to Section 6.1 “Alternate Pin Function” for
more information.

• Clear TMR1H and TMR1L registers.
• NOT set interrupt flag bit TMR1IF of the PIR1 register.
• Set the GO/DONE bit to start the ADC conversion

CCPx PIN CONFIGURATION
Clearing the CCPxCON register will force
the CCPx compare output latch to the
default low level. This is not the PORT I/O
data latch.

15.2.2
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.
15.2.3
When
(CCPxM<3:0> = 1010), the CCPxIF bit in the PIRx
register is set and the CCPx module does not assert
control of the CCPx pin (refer to the CCPxCON
register).
15.2.4
When Special Event Trigger mode is chosen
(CCPxM<3:0> = 1011), the CCPx module does the
following:
• Resets Timer1
• Starts an ADC conversion if ADC is enabled
The CCPx module does not assert control of the CCPx
pin in this mode (refer to the CCPxCON register).
The Special Event Trigger output of the CCP occurs
immediately upon a match between the TMR1H,
TMR1L register pair and the CCPRxH, CCPRxL
register pair. The TMR1H, TMR1L register pair is not
reset until the next rising edge of the Timer1 clock. This
allows the CCPRxH, CCPRxL register pair to
effectively provide a 16-bit programmable period
register for Timer1.
