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

TMR3CS<1:0>: Timer3 Clock Source Select bits
10 = Timer3 clock source is either from pin or oscillator, depending on the SOSCEN bit:
SOSCEN = 0 :
External clock is from T3CKI pin (on the rising edge).
SOSCEN = 1 :
Depending on the SOSCSEL Configuration bit, the clock source is either a crystal oscillator on
SOSCI/SOSCO or an internal digital clock from the SCLKI pin.

00 = 1:1 Prescale value
SOSCEN : SOSC Oscillator Enable bit
1 = SOSC enabled and available for Timer3
0 = SOSC disabled and available for Timer3
T3SYNC: Timer3 External Clock Input Synchronization Control bit
(Not usable if the device clock comes from Timer1/Timer3.)
When TMR3CS<1:0> = 10 :
1 = Do not synchronize external clock input
0 = Synchronize external clock input
When TMR3CS<1:0> = 0x :
This bit is ignored; Timer3 uses the internal clock.
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 eight-bit operations
