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.

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.

In This Book
This book describes the following products:
This book shows how to:
• Install and set up the emulation probe or emulation module.
• Connect the emulation probe/module to a target system.
• Configure the emulation probe/module for proper operation with your
target system.
• Use the emulation probe/module with debuggers.
This book also describes the specifications and characteristics of the
emulation probe/module, and it contains service information.
See Also If you’re using the Emulation Control Interface in the HP 16600A/
16700A-series logic analysis system to control the emulation probe/
module, see the logic analysis system’s on-line help.
If you’re using a high-level source debugger to control the emulation
probe/module, see the debugger’s documentation.
