PIC16F610/616/16HV610/616
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
bit 1 TMR1CS: Timer1 Clock Source Select bit
1 = External clock from T1CKI pin (on the rising edge)
0 = Internal clock
If TMR1ACS = 0:
FOSC/4
If TMR1ACS =
1:
FOSC
bit 0 TMR1ON: Timer1 On bit
1 = Enables Timer1
0 = Stops Timer1
Note 1: T1GINV bit inverts the Timer1 gate logic, regardless of source.
2: TMR1GE bit must be set to use either T1G
pin or C2OUT, as selected by the T1GSS bit of the CM2CON1
register, as a Timer1 gate source.
REGISTER 6-1: T1CON: TIMER1 CONTROL REGISTER (CONTINUED)
