TMR1CS<1:0>: Timer1 Clock Source Select bits
10 = Timer1 clock source is either from pin or oscillator, depending on the SOSCEN bit:
SOSCEN = 0 :
External clock is 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
SOSCI/SOSCO or an internal digital clock from the SCLKI pin.
01 = Timer1 clock source is system clock (F
00 = Timer1 clock source is 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 enabled and available for Timer1
0 = SOSC 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 .

The module derives its clocking source from either the
secondary oscillator or from an external digital source.
If using the secondary oscillator, there are the addi-
tional options for low-power, high-power and external,
digital clock source.
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>).
The F
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.
