PIC18F6585/8585/6680/8680
14.0
The Timer3 module timer/counter has the following
features:
• 16-bit timer/counter
• Readable and writable (both registers)
• Internal or external clock select
• Interrupt on overflow from FFFFh to 0000h
• Reset from CCP module trigger
REGISTER 14-1:
DS30491C-page 164
(two 8-bit registers; TMR3H and TMR3L)
TIMER3 MODULE
bit 7
bit 6, 3 T3CCP2:T3CCP1: Timer3 and Timer1 to CCPx Enable bits
bit 5-4
bit 2
bit 1
bit 0
T3CON: TIMER3 CONTROL REGISTER
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
1x = Timer3 is the clock source for compare/capture of CCP1 and CCP2 modules
01 = Timer3 is the clock source for compare/capture of CCP2 module,
00 = Timer1 is the clock source for compare/capture of CCP1 and CCP2 modules
T3CKPS1:T3CKPS0: 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 system 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
0 = Internal clock (F
TMR3ON: Timer3 On bit
1 = Enables Timer3
0 = Stops Timer3
bit 7

Figure 14-1 is a simplified block diagram of the Timer3
module.
Register 14-1 shows the Timer3 Control register. This
register controls the operating mode of the Timer3
module and sets the Enhanced CCP1 and CCP2 clock
source.
Register 12-1 shows the Timer1 Control register. This
register controls the operating mode of the Timer1
module, as well as containing the Timer1 oscillator
enable bit (T1OSCEN) which can be a clock source for
Timer3.
