13.2
The Timer1 oscillator may be used as the clock source
for Timer3. The Timer1 oscillator is enabled by setting
the T1OSCEN bit (T1CON Register). The oscillator is
a low power oscillator rated up to 200 kHz. Refer to
“Timer1 Module”, Section 11.0 for Timer1 oscillator
details.
13.3
The TMR3 Register pair (TMR3H:TMR3L) increments
from 0000h to FFFFh and rolls over to 0000h. The
TMR3 Interrupt, if enabled, is generated on overflow
which is latched in interrupt flag bit TMR3IF (PIR Reg-
isters). This interrupt can be enabled/disabled by set-
ting/clearing TMR3 interrupt enable bit TMR3IE (PIE
Registers).

13.4
If the CCP module is configured in Compare mode to
generate a “special event trigger" (CCP1M3:CCP1M0
= 1011), this signal will reset Timer3.
Timer3 must be configured for either timer or Synchro-
nized Counter mode to take advantage of this feature. If
Timer3 is running in Asynchronous Counter mode, this
RESET operation may not work. In the event that a write
to Timer3 coincides with a special event trigger from
CCP1, the write will take precedence. In this mode of
operation,
becomes the period register for Timer3. Refer to
“Capture/Compare/PWM (CCP) Modules”, Section 14.0
for CCP details.
