IMPORTANT
Notes on Downloading Firmware:•Before using this product for the first time, it is necessary to download the dedicated firmware
(control software for the emulation pod built into the PC4701). Please note that, to do this, it is
necessary to start up the PC4701 in the maintenance mode. For firmware download procedures, see
"4.2 Downloading Firmware" (page 48). 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.
•Except when a target status error occurs, if self-checks are not completed successfully, there may
be trouble with the product. In such case, contact your sales representative. However, perform self-
checks in the below setup.
(1) Target system: Not connected
(2) Emulation pod internal switches: At their factory settings
Notes on Target System:•The Vcc pin of emulator is connected to the target system to observe the voltage of the target system.
Therefore 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.
•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 emulator main unit,
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 emulator as simultaneously as possible.
(2) When the PC4701 and emulator debugger 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 target status LED (POWER) is ON.
For details, refer to "Chapter 4. Usage" (page 45).
Note on When the Emulator Debugger Ends:•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 Stack Area:•With this product, a maximum 8 bytes of the user stack is consumed.
•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 +8 bytes maximum
capacity used by the user program as the user stack area.
