The Timer3 timer/counter modules incorporate these
features:
• Software-selectable operation as a 16-bit timer or 

counter

• One 16-bit readable and writable Timer Value 

register

• Selectable clock source (internal or external) with 

device clock, SOSC or LPRC oscillator options

• Interrupt-on-overflow
• Multiple timer gating options, including:

- user-selectable gate sources and polarity
- gate/toggle operation
- Single-pulse (One-Shot) mode

• Module Reset on ECCP Special Event Trigger
The Timer3 module is controlled through the T3CON
register (

). A simplified block diagram of

the Timer3 module is shown in 

The F

OSC

 clock source should not be used with the

ECCP capture/compare features. If the timer will be
used with the capture or compare features, always
select one of the other timer clocking options.

This data sheet summarizes the features
of this group of PIC24F devices. It is not
intended to be a comprehensive refer-
ence source. For more information on
Timers, refer to the “PIC24F Family Refer-
ence Manual”
