T1GINV: Timer1 Gate Invert bit(1)

1 = Timer1 gate is inverted

0 = Timer1 gate is not inverted

TMR1GE: Timer1 Gate Enable bit(2)

If TMR1ON = 0:

This bit is ignored.

If TMR1ON = 1:

1 = Timer1 is on if Timer1 gate is not active

0 = Timer1 is on

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 CLKOUT 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 T1CKI pin (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: TMR1GE 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
