20.3
In Compare mode, the 16-bit CCPR1 register value is
constantly compared against the Timer register pair
value selected in the CCPTMR1 register. When a
match occurs, the ECCP1 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 (CCP1M<3:0>). At the same time, the
interrupt flag bit, CCP1IF, is set.
20.3.1
Users must configure the ECCP1 pin as an output by
clearing the appropriate TRIS bit.

ECCP PIN CONFIGURATION
Clearing the CCP1CON register will force

default low level. This is not the port I/O

20.3.2
Timer1, 2, 3 or 4 must be running in Timer mode or
Synchronized Counter mode if the ECCP module is
using the compare feature. In Asynchronous Counter
mode, the compare operation will not work reliably.
20.3.3
When the Generate Software Interrupt mode is chosen
(CCP1M<3:0> = 1010 ), the ECCP1 pin is not affected;
only the CCP1IF interrupt flag is affected.
20.3.4
The ECCP 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
(CCP1M<3:0> = 1011 ).
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 CCPR1 registers to
serve as a programmable Period register for either timer.
The Special Event Trigger can also start an A/D conver-
sion. In order to do this, the A/D Converter must
already be enabled.
