10.1
The 32-bit timer can be placed in the Gated Time
Accumulation mode. This mode allows the internal T
to increment the respective timer when the gate input
signal (T2CK pin) is asserted high. Control bit, TGATE
(T2CON<6>), must be set to enable this mode. When
in this mode, Timer2 is the originating clock source.
The TGATE setting is ignored for Timer3. The timer
must be enabled (TON = 1) and the timer clock source
set to internal (TCS = 0).
The falling edge of the external signal terminates the
count operation but does not reset the timer. The user
must reset the timer in order to start counting from zero.
10.2
When a match occurs between the 32-bit timer
(TMR3/TMR2) and the 32-bit combined period register
(PR3/PR2), or between the 16-bit timer TMR3 and the
16-bit period register PR3, a special ADC trigger event
signal is generated by Timer3.
10.3
The input clock (F
has a prescale option of 1:1, 1:8, 1:64, and 1:256,
selected by control bits, TCKPS<1:0> (T2CON<5:4>
and T3CON<5:4>). For the 32-bit timer operation, the
originating clock source is Timer2. The prescaler
operation for Timer3 is not applicable in this mode. The
prescaler counter is cleared when any of the following
occurs:
• A write to the TMR2/TMR3 register
• A write to the T2CON/T3CON register
• A device Reset, such as a POR and BOR
However, if the timer is disabled (TON = 0), the Timer
2 prescaler cannot be reset since the prescaler clock is
halted.
TMR2/TMR3 is not cleared when T2CON/T3CON is
written.

The timer does not operate during CPU Sleep mode
because the internal clocks are disabled.
10.5
The
interrupt-on-period match or on the falling edge of the
external gate signal. When the 32-bit timer count
matches the respective 32-bit period register, or the
falling edge of the external “gate” signal is detected, the
T3IF bit (IFS0<7>) is asserted and an interrupt is
generated if enabled. In this mode, the T3IF interrupt
flag is used as the source of the interrupt. The T3IF bit
must be cleared in software.
Enabling an interrupt is accomplished via the
respective timer interrupt enable bit, T3IE (IEC0<7>).
