No actually I don't see it. I see a picture of the Versa ECP5 with colored
circles and numbers, and I see the lattice table 12 with coloured squares
representing the wires next to the pin numbers, as well as the "viewed from
above PCB" diagram of the STLINKv2, and the corresponding table again with
colours representing the wires next to the pin numbers. I don't see anything
missing. I'm confused.
