R/W-0
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
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)
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.
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
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
This bit is automatically cleared when T1GSPM is cleared.
T1GVAL: Timer1 Gate Current State bit
Indicates the current state of the Timer1 gate that could be provided to TMR1H:TMR1L.
Unaffected by Timer1 Gate Enable (TMR1GE).
T1GSS<1:0>: Timer1 Gate Source Select bits
00 = Timer1 Gate pin
01 = Timer0 Overflow output
10 = TMR2 Match PR2 output
11 = Watchdog Timer scaler overflow
T1GPOL
R/W-0
Watchdog Timer oscillator is turned on if TMR1GE = 1, regardless of the state of TMR1ON
