( 8 / 52 )

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.

Warnings for Use Environment:

• The emulation pod is air-cooled with the ventilation slot. Therefore, do not block the ventilation
slot. When heated to high temperatures, the emulation pod may not work properly.

• 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 emulation pod main unit 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) for connecting to the emulator main unit and the flexible cable
(FLX100) for connecting the target system 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.

Cautions to Be Taken for Turning On the Power:

• Turn on the power of the emulator and target system as simultaneously as possible.

• Turn off the power of the emulator and target system as simultaneously as possible.

• Do not leave either the emulator or target system powered on, because of leakage current the
internal circuits may be damaged.

• When turning on the power again after shutting off the power, wait about 10 seconds.

( 9 / 52 )

IMPORTANT

Note on Malfunctions in the PC4701 System:

• If the emulator malfunctions because of interference like external noise, do the following to remedy
the trouble.

(1) Press the RESET switch on the emulator front panel.
(2) If normal operation is not restored after step (1), shut OFF power to the emulator once and then

reactivate it.

Notes on Downloading Firmware:

• Before using this product for the first time, it is necessary to download the dedicated firmware.
Please note that, to do this, it is necessary to start up the emulator main unit in maintenance mode.
For firmware download procedures, see "4.2 Downloading Firmware" (page 32). Once the
firmware has been downloaded, the product can be used by simply turning on the power.

• Do not shut off the power while downloading the firmware. If this happens, the product will not
start up properly. If power is shut off unexpectedly, redownload the firmware in maintenance mode.

• Be sure to disconnect the target system before downloading the firmware.

Notes on the Self-check:

• If the self-check does not result normally (except target status errors), the product may be damaged.
Then, contact your local distributor.

•Be sure to disconnect the target system before executing the self-check. For details on the self­check, see "4.4 Self-check" on page 34.

Note on Quitting the Emulator Debugger:

• To restart the emulator debugger after it ends, always shut power to the emulator module off once
and then on again.

Note on Final Evaluation:

• Be sure to evaluate your system with an evaluation MCU. Before starting mask production,
evaluate your system and make final confirmation with a CS (Commercial Sample) version MCU.

Notes on Power Supply to the Target System:

• The Vcc pin of the 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 emulator MCU is powered by the target system.

• The voltage of the target system should be within the range of the MCU specification and suit to
the emulator MCUs as shown below;

(1) For 5.0V version MCUs: +4.5 to +5.5 V
(2) For 3.3V version MCUs: +3.0 to +3.6 V

•Do not change the voltage of the target system after turning on the power.

( 10 / 52 )

Notes on EMEM Dialog:

• When setting the EMEM dialog box of the emulator debugger M3T-PD79, pay attention to the
following:

(1) Processor Mode

Specify a processor mode for the target MCU to be debugged. If the BYTE pin and MD0 pin
settings do not match the specified processor mode, 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. However, when
debugging in single-chip or memory expansion mode, emulation memory is automatically
allocated as a work area for spaces corresponding to flash ROM. Therefore, the usable
emulation memory size varies with the internal flash ROM capacity of the selected MCU.

Example: For MCUs with 512KB flash ROM
=> Emulation memory size = 768 KB (256 KB is used as work area)

* 256 KB of emulation memory in banks 0 to 3 cannot be allocated.

(3) ROM Address

Disable the allocated emulation memory against writes by the user program. RAMs that have
been mapped to external locations cannot be disabled against writes.

IMPORTANT

(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.

(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.

(6) Map Address

Set external or internal for the allocated emulation memory area.

EXTERNAL:Devices on the target system can be accessed.
INTERNAL: Emulation memory can be accessed.
