MSP430 Datasheet missing pins
Looks like a documentation error - I'm shocked! Get in touch with the sales department, they're usually pretty responsive to these sorts of thing, even for low quantity potential orders. Will they fix it in another release? Less likely; it takes a lot of effort to do a new document release, and they're not going to re-issue for a small oversight like this even if it seems like a fairly major omission when you're trying to work with the part.
