GENERAL INFORMATION
1.1 INTRODUCTION
The DragonBall TM -EZ (MC68EZ328) Application Development System (M68EZ328ADS) is
designed to supply users with an environment to develop MC68EZ328 based application
software. Moreover, this board can be used as a reference for real-life product design.
M68EZ328ADS provides several interface ports for application software and target board
debug purpose.
DragonBall TM -EZ ADS altogether has two versions released for customers. This is the sec-
ond version. The board design and layout in second version has been changed a great deal.
It includes simplifying the design for enhancing production quality and the easiness to use.
However, most of the interfaces to external peripherals remain unchanged in order to pro-
vide high degree of compatibility with previous version. For more details on the changes,
Please refer to Appendix A .
This document will discuss the usage and system details of the M68EZ328ADS v2.0.
