TMRxCS<1:0>
12-1, is used to control Timer1/3/5 and select
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:
01 = Timer1/3/5 clock source is system clock (F
00 = Timer1/3/5 clock source is instruction clock (F
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
TxSOSCEN: Secondary Oscillator Enable Control bit
1 = Dedicated Secondary oscillator circuit enabled
0 = Dedicated Secondary oscillator circuit disabled
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 (F
TMRxCS<1:0> = 0X
This bit is ignored. Timer1/3/5 uses the internal clock when TMRxCS<1:0> = 1X.
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
TMRxON: Timer1/3/5 On bit
1 = Enables Timer1/3/5
0 = Stops Timer1/3/5
R/W-0/u
Clears Timer1/3/5 Gate flip-flop
If TxSOSCEN = 0:
External clock from TxCKI pin (on the rising edge)
If TxSOSCEN = 1:
Crystal oscillator on SOSCI/SOSCO pins
TXCON: TIMER1/3/5 CONTROL REGISTER
W = Writable bit
x = Bit is unknown
‘0’ = Bit is cleared
