Does the UDS get used in part 2 of the lab? Because only 8 bits need be transferred, thus you only need A18..A1, and it will always be LDS?

So in the handout, where $1234 was placed at location $200000, the LDS was asserted. If UDS was asserted there would be garbage there?

I assume that in Part1 to transfer an upper byte, that it occupies D7..D4?

Thanks
Jim
