PIC18F87K90 FAMILY
18.3
In Compare mode, the 16-bit CCPR4 register value is
constantly compared against either the TMR1 or TMR3
register pair value. When a match occurs, the CCP4
pin can be:
• Driven high
• Driven low
• Toggled (high-to-low or low-to-high)
• Unchanged (that is, reflecting the state of the I/O
The action on the pin is based on the value of the mode
select bits (CCP4M<3:0>). At the same time, the
interrupt flag bit, CCP4IF, is set.
Figure 18-2 shows the Compare mode block diagram
18.3.1
The user must configure the CCPx pin as an output by
clearing the appropriate TRIS bit.
18.3.2
If the CCP module is using the compare feature in
conjunction with any of the Timer1/3/5/7 timers, the tim-
ers must be running in Timer mode or Synchronized
Counter mode. In Asynchronous Counter mode, the
compare operation may not work.

CCP PIN CONFIGURATION
Clearing the CCP4CON register will force
the RC1 or RE7 compare output latch
(depending on device configuration) to the
default low level. This is not the PORTC or
PORTE I/O data latch.
TIMER1/3/5/7 MODE SELECTION
Details of the timer assignments for the
CCP modules are given in Table 18-2 and
Table 18-3.
Preliminary
18.3.3
When the Generate Software Interrupt mode is chosen
(CCP4M<3:0> = 1010), the CCP4 pin is not affected.
Only a CCP interrupt is generated, if enabled, and the
CCP4IE bit is set.
18.3.4
Both CCP modules are equipped with a Special Event
Trigger. This is an internal hardware signal generated
in Compare mode to trigger actions by other modules.
The Special Event Trigger is enabled by selecting
the
(CCP4M<3:0> = 1011).
For either CCP module, the Special Event Trigger resets
the timer register pair for whichever timer resource is
currently assigned as the module’s time base. This
allows the CCPRx registers to serve as a programmable
period register for either timer.
The Special Event Trigger for CCP4 cannot start an
A/D conversion.

SPECIAL EVENT TRIGGER
The Special Event Trigger of ECCP1 can
start an A/D conversion, but the A/D
Converter needs to be enabled. For
