IMPORTANT
Note on Malfunctions in the PC4701 System:
• If the emulator malfunctions because of interference such as external noise, do the following to
remedy the trouble.
(1) Press the RESET button 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
(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 maintenance mode. For firmware download procedures, see
"4.2 Downloading Firmware" (page 34). 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 the self-check is not completed successfully, there may
be trouble with the product. In such case, contact your sales representative.
Notes on Target System:
• For starting up the emulation pod normally, the following are needed.
(1) Connection to the emulator MCU
(2) Power to the emulator MCU (Vcc and GND)
• The Vcc pin 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 MCU's specified range and between
+0.9 and 5.5 V.
•Do not change the voltage of the target system after turning on the power.
(3) Clock to the emulator MCU
(4) Processing RESET pin and Vref pin (if the MCU has it)
When debugging with M38000TL2-FPD, use either an open-drain type reset IC or a CR reset
circuit. The recommended pull-up value is about 10kΩ. The MCU can be reset by outputting
"L" to the target through the reset clip on the M38000TL2-FPD. However, if the reset circuit
on the target is an H-output type RESET IC, it cannot be set to "L" and the emulator will not
operate properly.
According to the MCU specifications, terminate the Vref pin properly.
• Before powering on your emulator system, check that the host machine, the PC4701, 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-PD38 start up, check the target status LEDs
on the emulator main unit's front panel to see if this product is ready to operate.
(For the target status LEDs on the emulator main unit's front panel when starting up the
PC4701, refer to "4.1 (3) LED Display When the PC4701 Starts Up Normally" on page 33.)
