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

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
Unimplemented: Read as ‘0’
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
T3CCP1: Timer3 and Timer1 to CCP1 Enable bits
1 = Timer3 is the clock source for compare/capture of ECCP1
0 = Timer1 is the clock source for compare/capture of ECCP1
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.
