The F
features.
TMRxCS<1:0>: Timerx Clock Source Select bits
10 = The Timer1 clock source is either a pin or an oscillator depending on the SOSCEN bit.
01 = Timerx clock source is the system clock (F
00 = Timerx clock source is the instruction clock (F
TxCKPS<1:0>: Timerx 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 Timerx (based on SOSCSEL fuses)
0 = SOSC is disabled for Timerx
TxSYNC: Timerx External Clock Input Synchronization Control bit
(Not usable if the device clock comes from Timer1/Timer3.)
When TMRxCS<1:0> = 10:
1 = Do not synchronize external clock input
0 = Synchronize external clock input
When TMRxCS<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 Timerx in one 16-bit operation
0 = Enables register read/write of Timerx in two 8-bit operations
TMRxON: Timerx On bit
1 = Enables Timerx
0 = Stops Timerx
TMRxCS0
OSC
R/W-0
SOSCEN = 0:
External clock is from the T1CKI pin (on the rising edge).
SOSCEN = 1:
Crystal oscillator is on the SOSCI/SOSCO pins.
clock source should not be selected if the timer will be used with the ECCP capture/compare
