Purpose of the H8/3003 Emulator
Features of the H8/3003 Emulator
Purpose of the
H8/3003 Emulator The H8/3003 Emulator is designed to replace the H8/3003
microprocessor in your target system so you can control operation of
the microprocessor in your application hardware (usually refer
to as the target system). The H8/3003 emulator performs just like the
H8/3003 microprocessor, but is a device that allows you to control the
H8/3003 microprocessor directly. These features allow you to easily
debug software before any hardware is available, and ease the task of
integrating hardware and software.

*1 When you do in-circuit emulation for H8/3001 with mode 3/4 or
H8/3004/5 with mode 3, you must use HP 64784-66509 shipped with
HP 64784J/K. Refer to the "In-Circuit Emulation" Chapter in this
manual for more details.
1-4 Introduction to the H8/3003 Emulator

The H8/3003 emulator is provided without any QFP adaptors and PGA
adaptor(HP 64784E) with QFP probe. To emulate each processor with
your target system, you need to purchase appropriate QFP adaptor or
PGA adaptor with QFP probe listed in Table 1-1. To purchase them,
contact your local HP sales representative.
You can buy HP 64797B low voltage adaptor to emulate each
processor running with supply voltage from 2.7 up to 5.25V input in
your target system. To buy HP 64797B, contact your local HP sales
representative.
The list of supported microprocessors in Table 1-1 is not necessarily
complete. To determine if your microprocessor is supported or not,
contact Hewlett-Packard.
Clock Speeds You can select whether the emulator will be clocked by the internal
clock source or by the external clock source on your target system.
When you select a clock input conforming to the specification of Table
1-2.
Refer to the "Configuration the Emulator" Chapter in this manual for
more details.

1-6 Introduction to the H8/3003 Emulator

Emulation memory The H8/3003 emulator is used with one of the following Emulation
Memory Cards.
HP 64726A 128K byte Emulation Memory Card
HP 64727A 512K byte Emulation Memory Card
HP 64728A 1M byte Emulation Memory Card
HP 64729A 2M byte Emulation Memory Card
You can define up to 16 memory ranges (at 512 byte boundaries and
least 512 byte in length.) The emulator occupies 6K byte, which is
used for monitor program and internal RAM of microprocessor mapped
as emulation RAM, leaving 122K, 506K, 1018K, 2042K byte of
emulation memory which you may use. You can characterize memory
range as emulation RAM (eram), emulation ROM (erom), target
system RAM (tram), target system ROM (trom), or guarded memory
(grd). The emulator generates an error message when accesses are
made to guarded memory locations. You can also configure the
emulator so that writes to memory defined as ROM cause emulator
execution to break out of target program execution.
Analysis The H8/3003 emulator is used with one of the following analyzers
which allows you to trace code execution and processor activity.
HP 64704A 80-channel Emulation Bus Analyzer
HP 64703A 64-channel Emulation Bus Analyzer and
16-channel State/Timing Analyzer.
HP 64794A/C/D Deep Emulation Bus Analyzer
The Emulation Bus Analyzer monitors the emulation processor using
an internal analysis bus. The HP 64703A 64-channel Emulation Bus
Analyzer and 16-channel State/Timing Analyzer allows you to probe
up to 16 different lines in your target system.
Registers You can display or modify the H8/3003 internal register contents. This
includes the ability to modify the program counter (PC) value so you
can control where the emulator starts a program run.
Breakpoints You can set the emulator/analyzer interaction so the emulator will
break to the monitor program when the analyzer finds a specific state or
states, allowing you to perform post-mortem analysis of the program
execution. You can also set software breakpoints in your program.
This feature is realized by inserting a special instruction into user
Introduction to the H8/3003 Emulator 1-7

program. One of undefined opcodes (5770 hex) is used as software
breakpoint instruction. Refer to the "Using Software Breakpoints"
section of "Getting Started" chapter for more information.
Reset Support The emulator can be reset from the emulation system under your
control; or your target system can reset the emulation processor.
Real Time Operation Real-time signifies continuous execution of your program at full rated
processor speed without interference from the emulator. (Such
interference occurs when the emulator needs to break to the monitor to
perform an action you requested, such as displaying target system
memory.) Emulator features performed in real time include: running
and analyzer tracing. Emulator features not performed in real time
include: display or modification of target system memory, load/dump
of target memory, display or modification of registers.
1-8 Introduction to the H8/3003 Emulator

Limitations,
Restrictions
Foreground Monitor Foreground monitor is not supported for the H8/3003 emulator.
DMA Support Direct memory access to the emulation by external DMAC is not
allowed.
Internal RAM of
H8/3005 When you emulate H8/3005 processor, you can’t use address 0fef10h -
0ff00fh (mode 1) and 0ffef10h - 0fff00fh (mode 3) as internal RAM.
These area are worked as external 8bit 3state area.
Watch Dog Timer in
Background Watch dog timer is suspended count up while the emulator is running
in background monitor.
Monitor Break at
Sleep/Standby Mode When the emulator breaks into the background monitor, sleep or
software standby mode is released. Then, PC indicates next address of
"SLEEP" instruction.
Hardware Standby
Mode Hardware standby mode is not supported for the H8/3003 emulator.
Hardware standby request from target system will give the emulator
reset signal.
Interrupts in
Background Cycles The H8/3003 emulator does not accept any interrupts while in
background monitor. Such interrupts are suspended while running the
background monitor, and will occur when context is changed to
foreground.
Reset Output Enable
Bit The RSTOE (Reset output enable bit) is used to determine whether the
H8/3003 processor outputs reset signal when the processor is reset by
the watch dog timer. However, the H8/3003 emulator ignores the
configuration of the RSTOE, and works as it is configured with the
modify configuration command.

H8/3003 Evaluation chip in the emulator.
