The Timer2/3 and Timer4/5 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 and Timer4/5 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)

Individually, all four 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, and
T4CON, T5CON registers. T2CON and T4CON are
shown in generic form in
T5CON are shown in
For 32-bit timer/counter operation, Timer2 and Timer4
are the least significant word (lsw); Timer3 and Timer5
are the most significant word (msw) of the 32-bit timers.

Note:
For 32-bit operation, T3CON and T5CON
control bits are ignored. Only T2CON and
T4CON control bits are used for setup and
control. Timer2 and Timer4 clock and gate
inputs are utilized for the 32-bit timer mod-
ules, but an interrupt is generated with the
Timer3 and Timer5 interrupt flags.
Only Timer2, 3, 4 and 5 can trigger a DMA
data transfer.
