0 means the data on AD11 to AD0 is stored before trigger.
1 means the data on AD11 to AD0 is stored after trigger.
The trigger event flag plays an important role in post-, delay-, about-
and pre-trigger acquisition modes. For detailed information, please
refer to Chapter 5.1 Analog Input Features.
Each A/D channel has its own input range, controlled by a gain code
stored in on-board RAM.
To change the A/D channel input range for a channel:
Write the same channel in Write BASE+4 bit 0 to bit 3 (the start
channel) and bit 8 to bit 11 (the stop channel).
Write the gain code to Write BASE+2 bit 0 to bit2.
Write 0 or 1 to Write BASE+2 bit 4 to set unipolar or bipolar input.
