C.3 Channel Number and A/D Data - BASE+0 and
BASE+1
BASE+0 and BASE+1 hold the result of A/D conversion data.
For PCI-1710/1710L/1710HG/1710HGL/1711/1711L, the 12 bits of data
from the A/D conversion are stored in BASE+1 bit 3 to bit 0 and
BASE+0 bit 7 to bit 0.BASE+1 bit 7 to bit 4 hold the source A/D
channel number.
