The Timer2/3 feature has three 2-bit timers that can
also be configured as two independent 16-bit timers
with selectable operating modes.
As a 32-bit timer, the Timer2/3 feature permits
operation in three modes:
• Two Independent 16-bit timers (e.g., Timer2 and
• Single 32-bit timer (Timer2/3)
• Single 32-bit synchronous counter (Timer2/3)
The Timer2/3 feature also supports:
• Timer gate operation
• Selectable prescaler settings
• Timer operation during Idle and Sleep modes
• Interrupt on a 32-bit period register match
• Time base for Input Capture and Output Compare
• ADC1 event trigger (Timer2/3 only)
Individually, all eight of the 16-bit timers can function as
synchronous timers or counters. They also offer the
features listed above, except for the event trigger. The
operating modes and enabled features are determined
by setting the appropriate bit(s) in the T2CON, T3CON
registers. T2CON registers are shown in generic form
in
Register
For 32-bit timer/counter operation, Timer2 is the least
significant word, and Timer3 is the most significant
word (msw) of the 32-bit timers.

For 32-bit operation, T3CON control bits
are ignored. Only T2CON control bits are
used for setup and control. Timer2 clock
and gate inputs are used for the 32-bit
timer modules, but an interrupt is
generated with the Timer3 interrupt flags.

To configure the Timer2/3 feature timers for 32-bit
operation:
1.
2.
3.
4.
5.
6.
The timer value at any point is stored in the register
pair, TMR3:TMR2, which always contains the msw of
the count, while TMR2 contains the lsw.
12.2
To configure any of the timers for individual 16-bit
operation:
1.
2.
3.
4.
5.
6.
Set the T32 control bit.
Select the prescaler ratio for Timer2 using the
TCKPS<1:0> bits.
Set the Clock and Gating modes using the
corresponding TCS and TGATE bits.
Load the timer period value. PR3 contains the
msw of the value, while PR2 contains the least
significant word (lsw).
If interrupts are required, set the interrupt enable
bit, T3IE. Use the priority bits, T3IP<2:0>, to set
the interrupt priority. While Timer2 controls the
timer, the interrupt appears as a Timer3
interrupt.
Set the corresponding TON bit.
Clear the T32 bit corresponding to that timer.
Select the timer prescaler ratio using the
TCKPS<1:0> bits.
Set the Clock and Gating modes using the TCS
and TGATE bits.
Load the timer period value into the PRx
register.
If interrupts are required, set the interrupt enable
bit, TxIE. Use the priority bits, TxIP<2:0>, to set
the interrupt priority.
Set the TON bit.
