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

TMRxGE: Timer1/3/5 Gate Enable bit
If TMRxON =

This bit is ignored
If TMRxON =

= Timer1/3/5 counting is controlled by the Timer1/3/5 gate function

= Timer1/3/5 counts regardless of Timer1/3/5 gate function

bit 6

TxGPOL: Timer1/3/5 Gate Polarity bit

= Timer1/3/5 gate is active-high (Timer1/3/5 counts when gate is high)

= Timer1/3/5 gate is active-low (Timer1/3/5 counts when gate is low)

bit 5

TxGTM: Timer1/3/5 Gate Toggle Mode bit

= Timer1/3/5 Gate Toggle mode is enabled

= Timer1/3/5 Gate Toggle mode is disabled and toggle flip-flop is cleared

Timer1/3/5 gate flip-flop toggles on every rising edge.

bit 4

TxGSPM: Timer1/3/5 Gate Single-Pulse Mode bit

= Timer1/3/5 gate Single-Pulse mode is enabled and is controlling Timer1/3/5 gate

= Timer1/3/5 gate Single-Pulse mode is disabled

bit 3

TxGGO/DONE: Timer1/3/5 Gate Single-Pulse Acquisition Status bit

= Timer1/3/5 gate single-pulse acquisition is ready, waiting for an edge

= Timer1/3/5 gate single-pulse acquisition has completed or has not been started

This bit is automatically cleared when TxGSPM is cleared.

bit 2

TxGVAL: Timer1/3/5 Gate Current State bit
Indicates the current state of the Timer1/3/5 gate that could be provided to TMRxH:TMRxL.
Unaffected by Timer1/3/5 Gate Enable (TMRxGE).

bit 1-0

TxGSS<1:0>: Timer1/3/5 Gate Source Select bits

= Timer1/3/5 Gate pin

= Timer2/4/6 Match PR2/4/6 output (See

Table 12-6

for proper timer match selection)

= Comparator 1 optionally synchronized output (sync_C1OUT)

= Comparator 2 optionally synchronized output (sync_C2OUT)
