4 versions in a week! Please slow down your pace. When you send a new
version, you move to the end of my review queue.

IIRC, these 2 chips are a bit different in what the mode switch or
muxing looks like. One had a built-in mux and the other doesn't? Do I
have to go research this again? No, you need to explain all this in
this series.
