About This Book
This user’s manual describes the features and operation of the MC68VZ328 (DragonBall™ VZ)
microprocessor, the third generation of the DragonBall family of pr oducts. It p rovide s the detai ls of how to
initialize, configure, and program the MC68VZ328. The manual presumes basic knowledge of 68000
architecture.
Audience
The MC68VZ328 user’s manual is intended to provide a design engineer with the necessary data to
successfully integrate the MC68VZ328 into a wide variety of applicat ions. I t is ass umed that t he reader has
a good working knowledge of the 68000 CPU. For programming information about the 68000, see the
documents listed in the Suggested Reading section of this preface.
Organization
The MC68VZ328 user’s manual is organized into 20 chapters that cover the op eration and prog ramming of
the DragonBall VZ device. Summaries of the chapters follow.
Chapter 1 Introduction: This chapter contains a device overview, system block diagrams,
and an operational overview of 68000 CPU operation.
Chapter 2 Signal Descriptions: This chapter contains listings of the MC68VZ328 input and
output signals, organized into functional groups.
Chapter 3 Memory Map: This chapter summarizes the memory organization,
programming information, and registers’ addresses and reset values.
Chapter 4 Clock Generation Module and Power Control Module: This chapter provides
detailed information about the operation and programming of the clock
generation module as well as the recommended circuit schematics for external
clock circuits. It also describes and provides programming information ab out the
operation of the power control module and the system power states.
Chapter 5 System Control: This chapter describes the operation of and programming
models for the system control, peripheral cont ro l, ID, and I/O drive control
registers.
Chapter 6 Chip-Select Logic: This chapter describes the operation and programming of the
chip-select logic. It includes information related to the operation of the DRAM
controller and other memory-related applications.
Chapter 7 DRAM Controller: The operation and programming of the DRAM controller is
described in this chapter. This module provides a glueless inte rface to 8-bit or
16-bit DRAM supporting EDO RAM, Fast Page Mode, and synchronous DRAM.
Chapter 8 LCD Controller: This chapter describes the operation and programming of the
LCD controller, which provides display data for external LCD drivers or for an
LCD panel.
