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.
