To our customers,
Old Company Name in Catalogs and Other Documents
On April 1st, 2010, NEC Electronics Corporation merged with Renesas Technology
Corporation, and Renesas Electronics Corporation took over all the business of both
companies. Therefore, although the old company name remains in this document, it is a valid
Renesas Electronics document. We appreciate your understanding.

crime systems; safety equipment; and medical equipment not specifically designed for life support.
“Specific”: Aircraft; aerospace equipment; submersible repeaters; nuclear reactor control systems; medical equipment or
systems for life support (e.g. artificial life support devices or systems), surgical implantations, or healthcare
intervention (e.g. excision, etc.), and any other applications or purposes that pose a direct threat to human life.
8. You should use the Renesas Electronics products described in this document within the range specified by Renesas Electronics,

CHAPTER 1 GENERAL
IE-78044-R-EM is an emulation board for the IE-78000-R development system for NEC’s
µ
PD78024 Subseries, 78044
Subseries, and 78044A Subseries 8-bit single-chip microcomputers. By combining this board with an optional IE-78000-
R with an emulation probe, the
µ
PD78024 Subseries, 78044 Subseries, and 78044A Subseries can be efficiently
emulated.
1.1 Features
The IE-78044-R-EM features, when it is connected to IE-78000-R, are as follows:
(1) Emulates the peripheral functions (such as I/O ports) for the target device
(2) Traces the I/O port status during emulation
(3) Controls mask option resistor connections and P04/XT1 pin switching through software
1.2 Unpacking
The IE-78044-R-EM shipping carton contains the following accessories, as well as IE-78044-R-EM. On unpacking,
confirm that these items are present.

1.6 Notes on correct use of IE-78044-R-EM
(1) Be sure to turn off the power to IE-78000-R and the target system before connecting or disconnecting IE-78000-
R and the target system, and changing the setting of switches.
(2) When emulating the target device by using IE-78044-R-EM and IE-78000-R, the target device operations slightly
differ from those for the actual device. (Refer to CHAPTER 3 DIFFERENCES BETWEEN TARGET DEVICES.)
(3) To input data through the external sense clip, maintain voltage at +15 V.
(4) To output data through the external sense clip, connect a pull-up resistor to the external sense clip on the target
system, because the external sense clip has an open-collector output configuration.
(5) Be sure to connect the emulation probe ground clip to the target system signal ground line.
(6) Pins P8 and P12 cannot be traced as port pins.
(7) 5V must be supplied to the target system as VDD.

CHAPTER 2 INSTALLATION
This chapter describes the procedure for installing the
µ
PD78024 Subseries, 78044 Subseries, and 78044A Subseries
development system with the IE-78044-R-EM connected to the following:
• Break board installed in IE-78000-R (IE-78000-R-BK)
• IE-78000-R
• Connector board and emulation probe (optional)
Before connecting these boards and probe, be sure to turn off the power to IE-78000-R and the target system.
For connecting the emulation probe to the target system, refer to CHAPTER 5 CONNECTING TARGET SYSTEM in
the IE-78000-R User’s Manual.

CHAPTER 2 INSTALLATION
Connect IE-78044-R-EM, break board, IE-78000-R, connector board, and emulation probe as follows:
(1) Remove the six screws from the top cover of IE-78000-R and remove the cover.
(2) Disconnect cables J1 and J2 connecting the control/trace board (IE-78000-R-CS-A) and break board.
(3) Pull the card pullers at both edges of the break board toward you, to pull out the break board from the slot.

CHAPTER 2 INSTALLATION
(4) Connect IE-78044-R-EM to the break board.
Connect connectors CN1 and CN2 on IE-78044-R-EM to mating connectors CN1 and CN2 on the break board.
Secure the connectors with the screws supplied as accessories.
Caution: Be sure to connect CN1 and CN2 securely.
(5) To use the user clock, mount the main system clock to the emulation board and the subsystem clock to the break
board by using the component block (refer to CHAPTER 4 SETTING CLOCK).
(6) Set the mask option by using the DIP switch on IE-78044-R-EM (refer to 3.1 Setting Mask Option).
(7) Connect connectors CN3 and CN4 for IE-78044-R-EM to mating connectors CN3 and CN4 on the connector board,
supplied with the optional emulation probe.
(8) Connect IE-78044-R-EM to the slot for the master board for the IE-78000-R’s housing (connect the break board
to the second slot from the right, and IE-78044-R-EM to the third slot from the right).
(9) Connect cables J1 and J2.
(10) Confirm the positions for the boards. Attach the top cover.
(11) Connect connector CN5, on top of IE-78000-R, to the mating connector CN5 on the emulation board. Secure the
connectors with screws.
