About this Manual
We’ve added this manual to the Agilent website in an effort to help you support
your product. This manual is the best copy we could find; it may be incomplete
or contain dated information. If we find a more recent copy in the future, we will
add it to the Agilent website.
Support for Your Product
Agilent no longer sells or supports this product. Our service centers may be able
to perform calibration if no repair parts are needed, but no other support from
Agilent is available. You will find any other available product information on the
Agilent Test & Measurement website, www.tm.agilent.com.
HP References in this Manual
This manual may contain references to HP or Hewlett-Packard. Please note that
Hewlett-Packard's former test and measurement, semiconductor products and
chemical analysis businesses are now part of Agilent Technologies. We have
made no changes to this manual copy. In other documentation, to reduce
potential confusion, the only change to product numbers and names has been in
the company name prefix: where a product number/name was HP XXXX the
current name/number is now Agilent XXXX. For example, model number
HP8648A is now model number Agilent 8648A.

Emulation for the PowerPC MPC500—At a Glance
Motorola’s embedded PowerPC MPC500 microprocessors provide a
development port (also known as a debug port) that lets tools like the
HP E3456A emulation probe or the HP 16610A emulation module give
you capabilities like:
• Stopping or starting program execution.
• Setting breakpoints in the program.
• Displaying and modifying the contents of microprocessor registers.
• Displaying and modifying the contents of target system memory or I/O.
• Downloading program code to target system memory.
The HP E3456A emulation probe and the HP 16610A emulation
module require that a debug port connector be designed into your
target system (unless you have the HP E2490A analysis probe for
MPC505/509 microprocessors which has a built-in connector for the
emulation probe or emulation module).
Both the HP E3456A emulation probe and the HP 16610A emulation
module come with a target interface module (TIM) that adapts the
emulation probe or emulation module to a debug port connector in the
target system.
The emulation probe or emulation module can be controlled by a
debugger on a host computer or by the Emulation Control Interface on
an HP 16600A/16700A-series logic analysis system.

3
Emulation Probe
The HP E3456A emulation probe is a stand-alone unit that has its own
power supply and local area network (LAN) interface.
The HP E3456A emulation probe is typically used in situations where
only its capabilities are needed, for example, by software developers
using debuggers to debug program code. But, it can also be used along
with the HP 16600A/16700A-series logic analysis system when logic
analysis capabilities are needed.
Emulation Module
The HP 16610A emulation module is designed to be installed in
HP 16600A/16700A-series logic analysis systems. The logic analysis
system supplies the power and LAN interface.
The HP 16610A emulation module is typically used in situations where
its capabilities are needed along with the logic analysis system
capabilities, for example, by hardware designers, firmware developers,
and system integrators who are analyzing the real-time execution of a
microprocessor-based target system.

Overview of Installation and Setup
Follow these steps to connect your equipment.
1Check that you received all of the necessary equipment. See
“Equipment and Requirements” on page 16.
2Disconnect power from the target system, emulation probe, and
logic analyzer before you make or break connections. See
“Powering-On and Powering-Off the Emulation Probe” on
page 19.
3Connect the emulation probe to a LAN. See “Connecting the
Emulation Probe to a LAN” on page 21.
4Update the emulation probe’s firmware to give it the proper
“personality” for the microprocessor it will connect to. See
“Updating Emulation Probe Firmware” on page 40.
5Connect the emulation probe to your target system. See the
“Connecting to a Target System” chapter on page 63.
6Configure the emulation probe. See the “Configuring the
Emulation Probe/Module” chapter on page 75.

Chapter 1: Installing the Emulation Probe
Equipment and Requirements
Equipment and Requirements
Listed below are:
• Equipment and software supplied with the emulation probe.
• Additional equipment and software required by the emulation probe.
Supplied Equipment and Software
The emulation probe includes:
• An emulation probe.
• A 12V power supply for the emulation probe.
•Apowercord.
• A target interface module (TIM) circuit board.
The target interface module (TIM) is used to connect the emulation probe
to a debug port connector in the target system.
The target interface module (TIM) is not needed when using the
HP E2490A analysis probe for MPC505/509 microprocessors because the
target interface module’s functionality is already built into the analysis
probe.
• A 50-pin ribbon cable for connecting the emulation module to the target
interface module (TIM) (or to the HP E2490A analysis probe).
• A 10-pin ribbon cable for connecting the target interface module (TIM) to
a debug port connector in the target system.
• Emulation Control Interface software.
• An emulation probe loopback test board (HP part number E3496-66502).
•ThisUser’s Guide.

17
Chapter 1: Installing the Emulation Probe
Equipment and Requirements
Additional Equipment and Software Required
The emulation probe requires:
• A target system with the appropriate debug port connector. The target
system must meet the criteria described in “Designing the Target System
for an Emulation Probe/Module” on page 64.
• A local area network (LAN) for communicating with the emulation probe.
The emulation probe needs to be assigned an internet (IP) address, and it
needs to know the IP address of the gateway machine.
• Interface software that gives you access to the emulation probe’s
functionality.
You can use a third-party high-level source debugger to access and control
the emulation module. Debuggers can run on PC or UNIX workstations
that are also on the local area network (LAN).
Or, you can use the HP 16600A/16700A-series logic analysis system’ s
Emulation Control Interface.

18
Chapter 1: Installing the Emulation Probe
Equipment and Requirements
Other Optional Equipment
You can also use the emulation probe with:
• The HP 16600A/16700A-series logic analysis system.
• The HP E2490A analysis probe for Motorola Embedded PowerPC MPC505/
509 microprocessors.
The analysis probe captures microprocessor signals for logic analysis. The
HP E2490A analysis probe has a built-in target interface module, which
makes it unnecessary to design a debug port connector into the target
system.
