TIMER3 MODULE
The F
The Timer1 oscillator crystal driver is powered whenever T1OSCEN (T1CON) or T3OSCEN (T3CON) = 1.
The circuit is enabled by the logical OR of these two bits. When disabled, the inverter and feedback resistor
are disabled to eliminate power drain. The TMR1ON and TMR3ON bits do not have to be enabled to power
up the crystal driver.
TMR3CS<1:0>: Timer3 Clock Source Select bits
10 = Timer3 clock source is the Timer1 oscillator or the T3CKI digital input pin (assigned in PPS module)
01 = Timer3 clock source is the system clock (F
00 = Timer3 clock source is the instruction clock (F
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
T3OSCEN: Timer3 Oscillator Source Select bit
When TMR3CS<1:0> = 10:
1 = Power up the Timer1 crystal driver (T1OSC) and supply the Timer3 clock from the crystal output
0 = Timer1 crystal driver off
When TMR3CS<1:0> = 0x:
1 = Power up the Timer1 crystal driver (T1OSC)
0 = Timer1 crystal driver off
T3SYNC: Timer3 External Clock Input Synchronization Control bit
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 8-bit operations

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.

timer will be used with the capture or compare features,
always select one of the other timer clocking options.
