CCP PRESCALER
There are four prescaler settings, specied by bits
CCP1M3:CCP1M0. Whenever the CCP module is
turned off, or the CCP module is not in Capture mode,
the prescaler counter is cleared. This means that any
reset will clear the prescaler counter.
Switching from one capture prescaler to another may
generate an interrupt. Also, the prescaler counter will
not be cleared, therefore the rst capture may be from
a non-zero prescaler. Example 10-1 shows the recom-
mended method for switching between capture pres-
calers. This example also clears the prescaler counter
and will not generate the “false” interrupt.

10.2
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 CCP1M3:CCP1M0 (CCP1CON<3:0>). At the
same time interrupt ag bit CCP1IF is set.

10.2.1
CCP PIN CONFIGURATION
The user must congure the RC2/CCP1 pin as an out-
put by clearing the TRISC<2> bit.
10.2.1
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.
10.2.2
SOFTWARE INTERRUPT MODE
When Generate Software Interrupt is chosen, the
CCP1 pin is not affected. Only a CCP interrupt is gen-
erated (if enabled).
10.2.3
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 and CCP2
resets the TMR1 register pair. This allows the
CCPR1H:CCPR1L and CCPR2H:CCPR2L registers to
effectively be 16-bit programmable period register(s)
for Timer1.
For compatibility issues, the special event trigger out-
put of CCP1 (PIC16C72) and CCP2 (all other
PIC16C7X devices) also starts an A/D conversion.
Note:
Clearing the CCP1CON register will force
the RC2/CCP1 compare output latch to the
default low level. This is not the data latch.
Note:
The “special
event
trigger” from
the
CCP1and CCP2 modules will not set inter-
rupt ag bit TMR1IF (PIR1<0>).
