Organization

Chapter 1

Introduction.  This chapter lists the H8/338 emulator features and
describes how they can help you in developing new hardware and
software.

Chapter 2

Getting Started.  This chapter shows you how to use emulation
commands by executing them on a sample program.  This chapter
describes the sample program and how to: load programs into the
emulator, map memory, display and modify memory, display registers,
step through programs, run programs, set software breakpoints, search
memory for data, and use the analyzer.

Chapter 3

In-Circuit Emulation.  This chapter shows you how to plug the
emulator into a target system, and how to use the "in-circuit" emulation
features.

Chapter 4

Configuring the Emulator.  You can configure the emulator to adapt
it to your specific development needs.  This chapter describes the
options available when configuring the emulator and how to save and
restore particular configurations.

Chapter 5

Using the Emulator.  This chapter describes emulation topics which
are not covered in the "Getting Started" chapter.
