TMR1CS1
R/W-0
13-1, is used to control Timer1 and select the
TMR1CS<1:0>: Timer1 Clock Source Select bits
11 = Reserved
10 = Timer1 clock source is pin or oscillator. External clock from T1CKI pin (on the rising edge)
01 = Timer1 clock source is system clock (F
00 = Timer1 clock source is instruction clock (F
T1CKPS<1:0>: Timer1 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
Unimplemented: Read as ‘0’
T1SYNC: Timer1 External Clock Input Synchronization Control bit
TMR1CS<1:0> = 1X
1 = Do not synchronize external clock input
0 = Synchronize external clock input with system clock (F
TMR1CS<1:0> = 0X
This bit is ignored. Timer1 uses the internal clock when TMR1CS<1:0> = 1X.
Unimplemented: Read as ‘0’
TMR1ON: Timer1 On bit
1 = Enables Timer1
0 = Stops Timer1
Clears Timer1 gate flip-flop
