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.

Chapter 1. Precautions for Safety
In both the user's manual and on the product itself, several icons are used to insure proper handling
of this product and also to prevent injuries to you or other persons, or damage to your properties.
This chapter describes the precautions which should be taken in order to use this product safely and
properly. Be sure to read this chapter before using this product.
1.1 Safety Symbols and Meanings

sentences are ignored, the equipment may
cause serious personal injury or death.
If the requirements shown in the "CAUTION"
sentences are ignored, the equipment may
malfunction.
It means important information on using this
product.
means WARNING or CAUTION.
Example: CAUTION AGAINST AN ELECTRIC SHOCK
means PROHIBITION.
Example: DISASSEMBLY PROHIBITED
means A FORCIBLE ACTION.
Example:
The following pages describe the symbols "WARNING", "CAUTION", and "IMPORTANT".
UNPLUG THE POWER CABLE FROM THE RECEPTACLE.
( 8 / 40 )
WARNING
Warning for Installation:
• Do not set this product in water or areas of high humidity. Spilling water or some other liquid into
the main unit can cause an unrepairable damage.
Warning for Use Environment:
• This equipment is to be used in an environment with a maximum ambient temperature of 35°C. Care
should be taken that this temperature is not exceeded.
CAUTION
Caution to Be Taken for Modifying This Product:
• Do not disassemble or modify this product. Disassembling or modifying this product can cause
damage. Disassembling and modifying the product will void your warranty.
Cautions to Be Taken for This Product:
• Use caution when handling the main unit. Be careful not to apply a mechanical shock.
• Do not touch the connector pins of the emulator main unit and the target MCU connector pins
directly. Static electricity may damage the internal circuits.
• Do not pull the pod probe by the flexible cable (FLX120-RPD) for connecting to the emulator main
unit or the flexible cable (FLX100) for connecting the target system. The cable may cause a break.
•Flexible cable FLX120-RPD and FLX100 are different from earlier models. The slits make them
more flexible. However, excessive flexing or force may break conductors.
•Do not use inch-size screws for this equipment. The screws used in this equipment are all ISO
(meter-size) type screws. When replacing screws, use same type screws as equipped before.
( 9 / 40 )
Notes on Target System:
• The Vcc pin of emulator is connected to the target system to observe the voltage of the target system.
Therefore the emulator cannot supply the power to the target system. Design your system so that
the target system is powered separately.
• The voltage of the target system should be within the range of the MCU specification and suit to
the emulator MCUs as shown below:
- For 5.0V version MCUs: +4.5 to +5.5V
•Do not change the voltage of the target system after turning on the power.
• Before powering on your emulator system, check that the host machine, the PC4701, M37900T2RPD-E, the converter board and target system are all connected correctly. Next, turn on the power
to each equipment following the procedure below.
(1) Turn ON/OFF the target system and the PC4701 as simultaneously as possible.
(2) When the PC4701 and emulator debugger M3T-PD79 start up, check the target status LEDs
on the emulator main unit's front panel to see if this product is ready to operate.
• Is the power supplied? Check that target status LED (POWER) is ON.
• Is the clock supplied? Check that target status LED (CLOCK) is ON.
IMPORTANT
Note on Reset Input from the Target System:
• The reset input from the target system is accepted only while a user program is being executed (only
while the RUN status LED on the PC4701's front panel is lit).
Notes on Stack Area:
• With this product, a maximum 26 bytes of the user stack is consumed as work area.
• If the user stack does not have enough area, do not use areas which cannot be used as stack (SFR
area, RAM area which stores data, or ROM area) as work area. Using areas like this is a cause of
user program crashes and destabilized emulator control. Therefore, ensure the +26 byte maximum
capacity used by the user program as the user stack area.
Note on MCU Files:
• When starting up the emulator debugger M3T-PD79, select the MCU file corresponding to the
MCU which is going to be debugged by Init dialog (MCU files are included with the emulator
debugger M3T-PD79).
MCU MCU file name
M37906F8 M37906F8.MCU
M37906M4 M37906M4.MCU
( 10 / 40 )
Notes on EMEM Dialog:
• When setting the EMEM dialog box of emulator debugger M3T-PD79, pay attention to the
following:
(1) Processor Mode
Specify a processor mode for the target MCU to be debugged. With 7906 Group MCUs, only
the single-chip mode is specifiable. If the MD0 pin setting is not "L" level, emulator debugger
M3T-PD79 outputs an error message. In such a case, check the pin settings on the target
system.
(2) Emem Address
Allocate the 1MB emulation memory that is included in the emulation pod. For the 7906
Group, it is not necessary to set this because this group operates only in the single-chip mode.
(3) ROM Address
Disable the allocated emulation memory against writes by the user program. For the 7906
Group, it is not necessary to set this because this group operates only in the single-chip mode.
(4) DMA Address
In this dialog box, set a transfer area when using the MCU's DMA function, and executing 1bus transfer between emulation memory and the target system. For the 7906 Group, do not set
such areas because this group does not have the DMA function.
IMPORTANT
(5) 8-bit bus mode Address
When accessing external data buses in 8-bit width using the chip select wait controller when
BYTE pin = Low, set this address for the relevant area. For the 7906 Group, it is not necessary
to set this because this group operates only in the single-chip mode.
(6) Map Address
Set external or internal for the allocated emulation memory area. For the 7906 Group, it is not
necessary to set this because this group operates only in the single-chip mode.
Note on Boot Mode:
• It is not possible to debug the MCUs in the boot mode using this emulator system.
(The MD1 pin of the MCU is fixed to the "L" level.)
Note on Breaks Used with Internal Resources:
•H/W breaks cannot be used with internal resources (SFR, internal RAM and internal flash ROM)
when using emulator PC4701L.
Note on Debug Monitor Area:
• The debug monitor area is fixed to the "FF" bank. It cannot be set to other banks.
