REGISTER 7-1:
T1CON: TIMER1 CONTROL REGISTER (ADDRESS 10h)
U-0
T1RUN
bit 7
bit 7
Unimplemented: Read as ‘0’
bit 6
T1RUN: Timer1 System Clock Status bit
1 = System clock is derived from Timer1 oscillator
0 = System clock is derived from another source
bit 5-4
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
bit 3
T1OSCEN: Timer1 Oscillator Enable Control bit
1 = Oscillator is enabled
0 = Oscillator is shut off (the oscillator inverter is turned off to eliminate power drain)
bit 2
T1SYNC: Timer1 External Clock Input Synchronization Control bit
TMR1CS = 1:
1 = Do not synchronize external clock input
0 = Synchronize external clock input
TMR1CS = 0:
This bit is ignored. Timer1 uses the internal clock when TMR1CS = 0.
bit 1
TMR1CS: Timer1 Clock Source Select bit
1 = External clock from pin RB6/AN5
0 = Internal clock (F
Note 1: Available on PIC16F88 devices only.
bit 0
TMR1ON: Timer1 On bit
1 = Enables Timer1
0 = Stops Timer1
