How to Use This Manual
1. Objective and Target Users
This manual was written to explain the hardware functions and electrical characteristics of this
LSI to the target users, i.e. those who will be using this LSI in the design of application
systems. Target users are expected to understand the fundamentals of electrical circuits, logic
circuits, and microcomputers.
This manual is organized in the following items: an overview of the product, descriptions of
the CPU, system control functions, and peripheral functions, electrical characteristics of the
device, and usage notes.
When designing an application system that includes this LSI, take all points to note into
account. Points to note are given in their contexts and at the final part of each section, and
in the section giving usage notes.
The list of revisions is a summary of major points of revision or addition for earlier versions.
It does not cover all revised items. For details on the revised points, see the actual locations
in the manual.
