These bits select one-of-two possible ADC Trigger Sources:

External (Digital)01

Disabled00
SourceTS0TS1
Note
: TS[1:0] should be set to 0 while setting up Pacer source and count values.
TGEN
This bit is used to enable External Trigger function
1 = External rising-edge Digital Trigger enabled.
0 = External Digital Trigger has no effect.
Note that the external trigger requires proper setting of the
TS[1:0]
and
TGEN
bits. Once these bits are set, the next rising edge will start a Paced ADC conversion.
Subsequent triggers will have no effect until external trigger flop is cleared (
XTRCL
).
BURSTE
This bit enables 330 kHz ADC Burst mode. Start/Stop channels are selected via
the CHLx, CHHx bits in ADC CTRL/STAT register at BADR1 + 2.
1 = Burst Mode enabled
0 = Burst Mode disabled
PRTRG
This bit enables ADC Pre-trigger Mode. This bit works with the ARM and FFM0
bits when using Pre-trigger mode.
1 = Enable Pre-trigger Mode
0 = Disable Pre-trigger Mode
XTRCL
A write-clear to reset the
XTRIG
flip-flop.
1 = Clear
XTRIG
status.
0 = No Effect.
