10.1
Timer Gate Operation
The 32-bit timer can be placed in the Gated Time Accu-
mulation mode. This mode allows the internal TCY 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
ADC Event Trigger
When a match occurs between the 32-bit timer (TMR3/
TMR2) and the 32-bit combined Period register (PR3/
PR2), a special ADC trigger event signal is generated
by Timer3.
10.3
Timer Prescaler
The input clock (FOSC/4 or external clock) to the timer
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 oper-
ation 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
device Reset, such as POR and BOR
However, if the timer is disabled (TON = 0), then the
Timer2 prescaler cannot be reset since the prescaler
clock is halted.
TMR2/TMR3 is not cleared when T2CON/T3CON is
written.
10.4
Timer Operation During Sleep
Mode
During CPU Sleep mode, the timer does not operate
because the internal clocks are disabled.
10.5
Timer Interrupt
The 32-bit timer module can generate an 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>).
