The Timer1 timer/counter module incorporates these
features:
• Software-selectable operation as a 16-bit timer or
• Readable and writable 8-bit registers (TMR1H
• Selectable clock source (internal or external) with
• Interrupt-on-overflow
• Reset on ECCP Special Event Trigger
• Timer with gated control

The F
TMR1CS<1:0>: Timer1 Clock Source Select bits
10 = The Timer1 clock source is either a pin or an oscillator depending on the SOSCEN bit.
SOSCEN = 0:
External clock is from the T1CKI pin (on the rising edge).
SOSCEN = 1:
Crystal oscillator is on the SOSCI/SOSCO pins or an extended clock on SCKLI (depends on SOSCEL
fuse, CONFIG1L<4:3>)
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 for Timer1 (based on SOSCSEL fuses)
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 the external clock input
0 = Synchronize the 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

Timer1 module.
The SOSC oscillator can also be used as a low-power
clock source for the microcontroller in power-managed
operation. Timer1 can also work on the SOSC oscillator.
Timer1 is controlled through the T1CON Control
register
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.
