The Timer3 module timer/counter 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 CCP Special Event Trigger
REGISTER 15-1:

TIMER3 MODULE
These bits and the ECCP module are available on PIC18F4X80 devices only.
RD16: 16-Bit Read/Write Mode Enable bit
1 = Enables register read/write of Timer3 in one 16-bit operation
0 = Enables register read/write of Timer3 in two 8-bit operations
T3ECCP1:T3CCP1: Timer3 and Timer1 to CCP/ECCP Enable bits
1x = Timer3 is the capture/compare clock source for both CCP and ECCP modules
01 = Timer3 is the capture/compare clock source for ECCP;
00 = Timer1 is the capture/compare clock source for both CCP and ECCP modules
T3CKPS<1:0>: Timer3 Input Clock Prescale Select bits
11 = 1:8 Prescale value
10 = 1:4 Prescale value
01 = 1:2 Prescale value
00 = 1:1 Prescale value
T3SYNC: Timer3 External Clock Input Synchronization Control bit
(Not usable if the device clock comes from Timer1/Timer3.)
When TMR3CS = 1:
1 = Do not synchronize external clock input
0 = Synchronize external clock input
When TMR3CS = 0:
This bit is ignored. Timer3 uses the internal clock when TMR3CS = 0.
TMR3CS: Timer3 Clock Source Select bit
1 = External clock input from Timer1 oscillator or T13CKI (on the rising edge after the first falling edge)
0 = Internal clock (F
TMR3ON: Timer3 On bit
1 = Enables Timer3
0 = Stops Timer3
T3ECCP1

Timer1 is the capture/compare clock source for CCP

A simplified block diagram of the Timer3 module is
shown in Figure 15-1. A block diagram of the module’s
operation in Read/Write mode is shown in Figure 15-2.
The Timer3 module is controlled through the T3CON
register (Register 15-1). It also selects the clock source
options for the CCP modules (see Section 16.1.1
“CCP Modules and Timer Resources” for more
information).
