14.2
The Timer1 oscillator may be used as the clock source
for Timer3. The Timer1 oscillator is enabled by setting
the T1OSCEN (T1CON<3>) bit. The oscillator is a low-
power oscillator rated for 32 kHz crystals. See
Section 12.2 “Timer1 Oscillator” for further details.
14.3
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
(PIR2<1>). This interrupt can be enabled/disabled by
setting/clearing TMR3 Interrupt Enable bit, TMR3IE
(PIE2<1>).

14.4
If the CCP module is configured in Compare mode
to generate
(CCP1M3:CCP1M0 = 1011), this signal will reset
Timer3. See Section 15.4.4 “Special Event Trigger”
for more information.
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, the CCPR1H:CCPR1L register pair
effectively becomes the period register for Timer3.
