features.
TMRxCS<1:0>: Timerx Clock Source Select bits
10 = Timer1 clock source depends on the SOSCEN bit:
SOSCEN = 0:
External clock from the T1CKI pin (on the rising edge).
SOSCEN = 1:
Depending on the SOSCSEL fuses, either a crystal oscillator on the SOSCI/SOSCO pins or an external
clock from the SCLKI pin.
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/SCLKI are enabled for Timerx (based on the SOSCSEL fuses)
0 = SOSC/SCLKI are disabled for Timerx and TxCKI is enabled
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 eight-bit operations
TMRxON: Timerx On bit
1 = Enables Timerx
0 = Stops Timerx
