9.2
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 RC2/CCP1 pin is:
Driven high
Driven low
Remains unchanged
The action on the pin is based on the value of control
bits CCP1M<3:0> (CCP1CON<3:0>). At the same
time, interrupt flag bit CCP1IF is set.

BLOCK DIAGRAM
9.2.1
CCP PIN CONFIGURATION
The user must configure the RC2/CCP1 pin as an out-
put by clearing the TRISC<2> bit.
9.2.2
TIMER1 MODE SELECTION
Timer1 must be running in Timer mode or Synchro-
nized Counter mode if the CCP module is using the
compare feature. In Asynchronous Counter mode, the
compare operation may not work.
9.2.3
SOFTWARE INTERRUPT MODE
When Generate Software Interrupt mode is chosen, the
CCP1 pin is not affected. The CCPIF bit is set causing
a CCP interrupt (if enabled).
9.2.4
SPECIAL EVENT TRIGGER
In this mode, an internal hardware trigger is generated,
which may be used to initiate an action.
The special event trigger output of CCP1 resets the TMR1
register pair. This allows the CCPR1 register to effectively
be a 16-bit programmable period register for Timer1.
The special event trigger output of CCP2 starts an A/D
conversion (if the A/D module is on) and resets the
TMR1 register pair and starts an A/D conversion (if the
A/D module is enabled).
9.3
PWM Mode (PWM)
In pulse width modulation mode, the CCPx pin pro-
duces up to a 10-bit resolution PWM output. Since the
CCP1 pin is multiplexed with the PORTC data latch, the
TRISC<2> bit must be cleared to make the CCP1 pin
an output.
Figure 9-3 shows a simplified block diagram of the
CCP module in PWM mode.
For a step by step procedure on how to set up the CCP
module for PWM operation, see Section 9.3.3.
FIGURE 9-3:
SIMPLIFIED PWM BLOCK
DIAGRAM
A PWM output (Figure 9-4) has a time base (period) and
a time that the output stays high (duty cycle). The fre-
quency of the PWM is the inverse of the period (1/period).
Note:
Clearing the CCP1CON register will force
the RC2/CCP1 compare output latch to the
default low level. This is not the data latch.

Special event trigger will:
reset Timer1, but not set interrupt flag bit TMR1IF (PIR1<0>),
and set bit GO/DONE (ADCON0<2>).
Note:
The

trigger
from
the
CCP1and CCP2 modules will not set inter-
rupt flag bit TMR1IF (PIR1<0>).
Note:
Clearing the CCP1CON register will force
the CCP1 PWM output latch to the default
low level. This is not the PORTC I/O data
latch.
