PIC18F47J53 FAMILY
15.6
The TMRx register pair (TMRxH:TMRxL) increments
from 0000h to FFFFh and overflows to 0000h. The
Timerx interrupt, if enabled, is generated on overflow
and is latched in the interrupt flag bit, TMRxIF.
Table 15-3 gives each module’s flag bit.
TABLE 15-3:
This interrupt can be enabled or disabled by setting or
clearing the TMRxIE bit, respectively. Table 15-4 gives
each module’s enable bit.

If the ECCP modules are configured to use Timerx and
to generate a Special Event Trigger in Compare mode
(CCPxM<3:0> = 1011), this signal will reset Timerx.
The trigger from ECCP2 will also start an A/D conver-
sion if the A/D module is enabled. (For more informa-
tion, see Section 19.3.4 “Special Event Trigger”.)
The module must be configured as either a timer or
synchronous counter to take advantage of this feature.
When used this way, the CCPRxH:CCPRxL register
pair effectively becomes a Period register for TimerX.
If Timerx is running in Asynchronous Counter mode,
the Reset operation may not work.
In the event that a write to Timerx coincides with a
Special Event Trigger from an ECCP module, the write
will take precedence.
Note:
Note:
Resetting Timer3/5 Using the
ECCP Special Event Trigger
The Special Event Triggers from the
ECCPx module will only clear the TMR3
register’s content, but not set the TMR3IF
interrupt flag bit (PIR1<0>).
The CCP and ECCP modules use Timers
1 through 8 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 CCPTMRSx registers.
For more details, see Register 19-2 and
Register 18-3.
