TMR1CS<1:0>: Timer1 Clock Source Select bits
10 = Timer1 clock source is either from a pin or oscillator,depending on the SOSCEN bit:
SOSCEN = 0:
External clock from the T1CKI pin (on the rising edge).
SOSCEN = 1:
Depending on the SOSCSEL Configuration bit the clock source is either a crystal oscillator on the
SOSCI/SOSCO pins or an internal clock from the SCLKI pin.
01 = Timer1 clock source is the system clock (F
00 = Timer1 clock source is the instruction clock (F
T1CKPS<1:0>: Timer1 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
SOSCEN: SOSC Oscillator Enable bit
1 = SOSC is enabled and available for Timer1
0 = SOSC is disabled for Timer1
The oscillator inverter and feedback resistor are turned off to eliminate power drain.
T1SYNC: Timer1 External Clock Input Synchronization Select bit
TMR1CS<1:0> = 10:
1 = Do not synchronize external clock input
0 = Synchronize external clock input
TMR1CS<1:0> = 0x:
This bit is ignored. Timer1 uses the internal clock when TMR1CS<1:0> = 1x.
RD16: 16-Bit Read/Write Mode Enable bit
1 = Enables register read/write of Timer1 in one 16-bit operation
0 = Enables register read/write of Timer1 in two 8-bit operations
TMR1ON: Timer1 On bit
1 = Enables Timer1
0 = Stops Timer1

SOSCEN
Figure 14-1 displays a simplified block diagram of the
Timer1 module.
The Timer1 oscillator can also be used as a low-power
clock source for the microcontroller in power-managed
operation. The Timer1 can also work on the SOSC
oscillator.
Timer1 is controlled through the T1CON Control
register (Register 14-1). It also contains the Secondary
Oscillator Enable bit (SOSCEN). Timer1 can be
enabled or disabled by setting or clearing control bit,
TMR1ON (T1CON<0>).

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