T1GINV: Timer1 Gate Invert bit⁽¹⁾
1 = Timer1 gate is inverted
0 = Timer1 gate is not inverted
T1GE: Timer1 Gate Enable bit⁽²⁾
If TMR1ON = 0:
This bit is ignored.
If TMR1ON = 1:
1 = Timer1 gate is enabled
0 = Timer1 gate is disabled
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
T1OSCEN: LP Oscillator Enable Control bit
If INTOSC without CLKO oscillator is active:
1 = LP oscillator is enabled for Timer1 clock
0 = LP oscillator is off
Else:
This bit is ignored.
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.
TMR1CS: Timer1 Clock Source Select bit
1 = External clock from RC5/T1CKI/CCP1/SEG10 pin or T1OSC (on the rising edge)
0 = Internal clock (FOSC/4)
TMR1ON: Timer1 On bit
1 = Enables Timer1
0 = Stops Timer1
Note 1: T1GINV bit inverts the Timer1 gate logic, regardless of source.
2: T1GE bit must be set to use either T1G pin or C2OUT, as selected by the T1GSS
bit (CMCON1<1>), as a Timer1 gate source.
Legend:
R = Readable bit
- n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared x = Bit is unknown
