bit 7

bit 0

Legend:

R = Readable bit

W = Writable bit

U = Unimplemented bit, read as ‘0’

u = Bit is unchanged

x = Bit is unknown

-n/n = Value at POR and BOR/Value at all other Resets

‘1’ = Bit is set

‘0’ = Bit is cleared

HC = Bit is cleared by hardware

bit 7

TMR1GE: Timer1 Gate Enable bit

If TMR1ON = 0:

This bit is ignored

If TMR1ON = 1:

1 = Timer1 counting is controlled by the Timer1 gate function

0 = Timer1 counts regardless of Timer1 gate function

bit 6

T1GPOL: Timer1 Gate Polarity bit

1 = Timer1 gate is active-high (Timer1 counts when gate is high)

0 = Timer1 gate is active-low (Timer1 counts when gate is low)

bit 5

T1GTM: Timer1 Gate Toggle Mode bit

1 = Timer1 Gate Toggle mode is enabled

0 = Timer1 Gate Toggle mode is disabled and toggle flip-flop is cleared

Timer1 gate flip-flop toggles on every rising edge.

bit 4

T1GSPM: Timer1 Gate Single-Pulse Mode bit

1 = Timer1 gate Single-Pulse mode is enabled and is controlling Timer1 gate

0 = Timer1 gate Single-Pulse mode is disabled

bit 3

T1GGO/DONE: Timer1 Gate Single-Pulse Acquisition Status bit

1 = Timer1 gate single-pulse acquisition is ready, waiting for an edge

0 = Timer1 gate single-pulse acquisition has completed or has not been started

bit 2

T1GVAL: Timer1 Gate Value Status bit

Indicates the current state of the Timer1 gate that could be provided to TMR1H:TMR1L.

Unaffected by Timer1 Gate Enable (TMR1GE).

bit 0

T1GSS<1:0>: Timer1 Gate Source Select bits

11 = Comparator 2 optionally synchronized output (C2OUT_sync)

10 = Comparator 1 optionally synchronized output (C1OUT_sync)

01 = Timer0 overflow output (T0_overflow)

00 = Timer1 gate pin (T1G)
