I really gotta start actually looking at the page numbers at the bottom before looking for new posts. Anyway, now that I know there are tons of replies to this:
I was on a long adventure through
this old topic again, now understanding most of the comments here and actually reading them rather than skimming them like the first 2 times I went through it. I had deduced from this that it would indeed be the 573 that needed qualifying, since that is the part that happens in phi2 low, and the '816 is held in the phi2 high state when RDY is low. Also, the 245 isn't even a latch (silly me). It seems you're referring to the very thread I was going through Dr. Jefyll, and, although it doesn't mention wait states, it should most certainly be part of any newbies journey to implementing an 816. After all this is said and done, I may try and compile some of the resources I've used for making this, and add a supplementary to Garth's primer, from the newbies point of view.
So, with this figured out, it should be pretty straight forward to do the wait states, all I need is RDY high qualified with PHI2 low on the 573.
A side note, I saw ABT and FCT devices mentioned in that thread, I looked them up, they look really fast and cheap (at least the ABT ones do). I see the technology is BiCMOS...I don't suppose this will cause any problems, or that a newer tech has been released that's even faster (maybe this question should go in my newbie thread)
