Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown

TMRxCS<1:0>: Clock Source Select bits
10 = Clock source is the pin or TxCKI input pin
01 = Clock source is the system clock (FOSC)⁽¹⁾
00 = Clock source is the instruction clock (FOSC/4)
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
TxOSCEN: Timer Oscillator Enable bit
1 = T1OSC/SOSC oscillator used as clock source
0 = TxCKI digital input pin used as clock source
TxSYNC: External Clock Input Synchronization Control bit
(Not usable if the device clock comes from Timer1/Timer3.)
When TMRxCS1:TMRxCS0 = 10:
1 = Do not synchronize external clock input
0 = Synchronize external clock input
When TMRxCS1:TMRxCS0 = 0x:
This bit is ignored; Timer3 uses the internal clock.
RD16: 16-Bit Read/Write Mode Enable bit
1 = Enables register read/write of timer in one 16-bit operation
0 = Enables register read/write of timer in two eight-bit operations
TMRxON: Timer On bit
1 = Enables Timer
0 = Stops Timer
Note 1: The FOSC clock source should not be selected if the timer will be used with the ECCP capture/compare
features.
