PIC18F66K80 FAMILY
16.6
The TMR3 register pair (TMR3H:TMR3L) increments
from 0000h to FFFFh and overflows to 0000h. The
Timer3 interrupt, if enabled, is generated on overflow
and is latched in the interrupt flag bit, TMR3IF.
Table 16-3
This interrupt can be enabled or disabled by setting or
clearing the TMR3IE bit.
module’s enable bit.
16.7
If the ECCP modules are configured to use Timer3 and
to generate a Special Event Trigger in Compare mode
(CCP3M<3:0> = 1011 ), this signal will reset Timer3.
The trigger from ECCP will also start an A/D conversion
if the A/D module is enabled (For more information, see

The module must be configured as either a timer or
synchronous counter to take advantage of this feature.
When used this way, the CCPR3H:CCPR3L register
pair effectively becomes a Period register for Timer3.
If Timer3 is running in Asynchronous Counter mode,
the Reset operation may not work.
In the event that a write to Timer3 coincides with a
Special Event Trigger from an ECCP module, the write
will take precedence.

Bit 3
The Special Event Triggers from the
ECCPx module will only clear the TMR3
register’s content, but not set the TMR3IF
interrupt flag bit (PIR2<1>).
The CCP and ECCP modules use Timers,
1 through 4, for some modes. The assign-
ment of a particular timer to a CCP/ECCP
module is determined by the Timer to CCP
enable bits in the CCPTMRS register. For
