No known info on converting this to real voltages?  I'd normally expect
a scale parameter at least with any raw channel output, but fair enough
if it's not obvous what this should be.

We know the internal reference voltage.
We can also know the external reference voltage by representing it as a 
regulator.

Since there are many combinations should a regulator for each 
reference(external reference, xp, yp, xn and yn) be used?
