For the most part, the H8/329 and H8/338 emulators all operate the

same way. Differences between the emulators are described where they

exist. Both the H8/329 and H8/338 emulators will be referred to as the

"H8/338 emulator". In the specific instances where H8/329 emulator

differs from H8/338 emulator, it will be described as the "H8/329

emulator".

This manual:

Shows you how to use emulation commands by executing

them on a sample program and describing their results.

Shows you how to use the emulator in-circuit (connected to a

target system).

Shows you how to configure the emulator for your

development needs. Topics include: restricting the emulator

to real-time execution, selecting a target system clock source.

This manual does not:

Show you how to use every Softkey Interface command and

option; the Softkey Interface is described in the Softkey

Interface Reference.

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.

Conventions Example commands throughout the manual use the following

conventions:

bold Commands, options, and parts of command syntax.

bold italic
