Timer3/5 Gate Control Register
Programming the TxGCON prior to TxCON is recommended.
TMRxGE: Timer Gate Enable bit
If TMRxON = 0:
This bit is ignored.
If TMRxON = 1:
1 = Timer counting is controlled by the Timerx gate function
0 = Timer counts regardless of the Timerx gate function
TxGPOL: Gate Polarity bit
1 = Timer gate is active-high (Timerx counts when the gate is high)
0 = Timer gate is active-low (Timerx counts when the gate is low)
TxGTM: Gate Toggle Mode bit
1 = Timer Gate Toggle mode is enabled.
0 = Timer Gate Toggle mode is disabled and toggle flip-flop is cleared
Timerx gate flip-flop toggles on every rising edge.
TxGSPM: Timer Gate Single Pulse Mode bit
1 = Timer Gate Single Pulse mode is enabled and is controlling Timerx gate
0 = Timer Gate Single Pulse mode is disabled
TxGGO/TxDONE: Timer Gate Single Pulse Acquisition Status bit
1 = Timer gate single pulse acquisition is ready, waiting for an edge
0 = Timer gate single pulse acquisition has completed or has not been started
This bit is automatically cleared when TxGSPM is cleared.
TxGVAL: Timer Gate Current State bit
Indicates the current state of the Timer gate that could be provided to TMRxH:TMRxL. Unaffected by the
Timer Gate Enable bit (TMRxGE).
