ZiLOG recommends that the user read and understand everything in this
manual before setting up and using the product. However, we recognize
that users have different styles of learning: some will want to set up and
use their new evaluation kit while they read about it; others will open
these pages only to check on a particular specification. Therefore, we
have designed this manual to be used either as a how to procedural
manual or a reference guide to important data.
