O.K. I found the error in the multiple A-Ds on the PIC.

If you set bit 1 in ADCON0 the A-D returns 0X3FF.
I suspect they meant to mark this bit as the identifier to the "reserved, do not select"
So every other analog channel select address is valid.

The NEW truth table is:

Bits 5-3,1
0000 = AN0
0001 = reserved, do not select
0010 = AN1
0011 = reserved, do not select
etc.

O.K. Microchip, where's my Sam Adams?
