Timer3/5/7 Gate Control Register
Programming the TxGCON prior to TxCON is recommended.
Timer(x+1) will be Timer4/6/8 or Timerx Timer3/5/7, respectively.
TMRxGE: Timerx Gate Enable bit
If TMRxON = 0:
This bit is ignored.
If TMRxON = 1:
1 = Timerx counting is controlled by the Timerx gate function
0 = Timerx counts regardless of the Timerx gate function
TxGPOL: Timerx Gate Polarity bit
1 = Timerx gate is active-high (Timerx counts when the gate is high)
0 = Timerx gate is active-low (Timerx counts when the gate is low)
TxGTM: Timerx Gate Toggle Mode bit
1 = Timerx Gate Toggle mode is enabled.
0 = Timerx Gate Toggle mode is disabled and toggle flip-flop is cleared
Timerx gate flip-flop toggles on every rising edge.
TxGSPM: Timerx Gate Single Pulse Mode bit
1 = Timerx Gate Single Pulse mode is enabled and is controlling the Timerx gate
0 = Timerx Gate Single Pulse mode is disabled
TxGGO/TxDONE: Timerx Gate Single Pulse Acquisition Status bit
1 = Timerx gate single pulse acquisition is ready, waiting for an edge
0 = Timerx gate single pulse acquisition has completed or has not been started
This bit is automatically cleared when TxGSPM is cleared.
TxGVAL: Timerx Gate Current State bit
Indicates the current state of the Timerx gate that could be provided to TMRxH:TMRxL. Unaffected by the
Timerx Gate Enable (TMRxGE) bit.
TxGSS<1:0>: Timerx Gate Source Select bits
11 = Comparator 2 output
10 = Comparator 1 output
01 = TMR(x + 1) to match PR(x + 1) output
00 = Timer1 gate pin
Watchdog Timer oscillator is turned on if TMRxGE = 1, regardless of the state of TMRxON.
