13.0
The Timer2/3, Timer4/5, Timer6/7 and Timer8/9
modules are 32-bit timers, which can also be
configured as four independent 16-bit timers with
selectable operating modes.
As a 32-bit timer, Timer2/3, Timer4/5, Timer6/7 and
Timer8/9 operate in three modes:
• Two Independent 16-bit Timers (e.g., Timer2 and
• Single 32-bit Timer
• Single 32-bit Synchronous Counter
They also support these features:
• 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)
• ADC2 Event Trigger (Timer4/5 only)

Preliminary
in
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; this
is implemented only with Timer2/3. The operating
modes and enabled features are determined by setting
the appropriate bit(s) in the T2CON, T3CON, T4CON,
T5CON, T6CON, T7CON, T8CON and T9CON
registers. T2CON, T4CON, T6CON and T8CON are
shown in generic form in
T5CON,
Register
For 32-bit timer/counter operation, Timer2, Timer4,
Timer6 or Timer8 is the least significant word; Timer3,
Timer5, Timer7 or Timer9 is the most significant word
of the 32-bit timers.

T7CON
For 32-bit operation, T3CON, T5CON,
T7CON and T9CON control bits are
ignored. Only T2CON, T4CON, T6CON
and T8CON control bits are used for setup
and control. Timer2, Timer4, Timer6 and
Timer8 clock and gate inputs are utilized
for the 32-bit timer modules, but an
interrupt is generated with the Timer3,
Timer5, Ttimer7 and Timer9 interrupt
flags.
Only Timer2, 3, 4 and 5 can trigger a DMA
data transfer.
