Was looking at T1CON register and noticed this:
TxCKPS<1:0>: Timer1/3/5 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
So that is 2 bits.
Code:
bit 7-6 TMRxCS<1:0>: Timer1/3/5 Clock Source Select bits
11 =Reserved. Do not use.
10 =Timer1/3/5 clock source is pin or oscillator:
If TxSOSCEN = 0:
External clock from TxCKI pin (on the rising edge)
If TxSOSCEN = 1:
Crystal oscillator on SOSCI/SOSCO pins
01 =Timer1/3/5 clock source is system clock (FOSC)
00 =Timer1/3/5 clock source is instruction clock (FOSC/4)
bit 5-4 TxCKPS<1:0>: Timer1/3/5 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
bit 3 TxSOSCEN: Secondary Oscillator Enable Control bit
1 = Dedicated Secondary oscillator circuit enabled
0 = Dedicated Secondary oscillator circuit disabled
bit 2 TxSYNC: Timer1/3/5 External Clock Input Synchronization Control bit
TMRxCS<1:0> = 1X
1 = Do not synchronize external clock input
0 = Synchronize external clock input with system clock (FOSC)
TMRxCS<1:0> = 0X
This bit is ignored. Timer1/3/5 uses the internal clock when TMRxCS<1:0> = 1X.
bit 1 TxRD16: 16-Bit Read/Write Mode Enable bit
1 = Enables register read/write of Timer1/3/5 in one 16-bit operation
0 = Enables register read/write of Timer1/3/5 in two 8-bit operation
bit 0 TMRxON: Timer1/3/5 On bit
1 = Enables Timer1/3/5
0 = Stops Timer1/3/5
Clears Timer1/3/5 Gate flip-flop
T1CON=00000000
