The Timer3 timer/counter module incorporates these
features:
• Software selectable operation as a 16-bit timer or
• Readable and writable 8-bit registers (TMR3H
• Selectable clock source (internal or external) with
• Interrupt-on-overflow
• Module Reset on ECCP Special Event Trigger

A simplified block diagram of the Timer3 module is
shown in Figure 14-1.
The Timer3 module is controlled through the T3CON
register (Register 14-1). It also selects the clock source
options for the ECCP modules; see Section 17.1.1
“ECCP Module and Timer Resources” for more
information.
The F
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.
