13.3
In Compare mode, the 16-bit CCPR1 register value is
constantly compared against the TMR1 register pair
value. When a match occurs, the CCP1 pin can be:
• driven high
• driven low
• toggled (high-to-low or low-to-high)
• remain unchanged (that is, reflects the state of the
The action on the pin is based on the value of the mode
select bits (CCP1M3:CCP1M0). At the same time, the
interrupt flag bit, CCP1IF, is set.
13.3.1
The user must configure the CCP1 pin as an output by
clearing the appropriate TRIS bit.

13.3.3
When the Generate Software Interrupt mode is chosen
(CCP1M3:CCP1M0 = 1010), the CCP1 pin is not
affected. Only a CCP interrupt is generated, if enabled,
and the CCP1IE bit is set.
13.3.4
The CCP module is 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
(CCP1M3:CCP1M0 = 1011).
For the CCP module, the Special Event Trigger resets
the Timer1 register pair. This allows the CCPR1
registers to serve as a programmable period register
for the Timer1.
The Special Event Trigger for CCP1 can also start an
A/D conversion. In order to do this, the A/D Converter
must already be enabled.
