Notes on the User System (Power Supply, Order of Powering On):
• For starting up the emulator normally, the following are needed.
• If the self-check does not result normally, the emulator may be damaged. Then contact your local distributor.
• Run the self-check with the user system connected.
• To restart the emulator debugger, always shut power to the emulator main unit off once and then on again.
• Do not shut OFF power while firmware is being downloaded. Doing so, the emulator will not start up properly.
• The clock supplied to the emulator MCU is available from only the oscillator circuit in the user system.
• Before powering on your emulator system, check that the host machine, the emulator, the converter board and
Whether RESET operation on the emulator MCU is possible? Check that target status LED (RESET) is OFF.

(1) Turn ON/OFF the user system and the emulator as simultaneously as possible.
(2) When the emulator debugger starts up, check the target status LEDs on the emulator to see if this product

is ready to operate.
- The Vcc pin is connected to the user system to observe the voltage of the user system. Therefore the
- The voltage of the user system should be within the MCU’s specified range and between +1.8 to 5.0 V.
- Do not change the voltage of the user system after turning on the power.
When debugging with the M38000T2-CPE, use either an open-drain type reset IC or CR reset circuit. The
recommended pull-up value is about 10kΩ. The MCU can be reset by outputting “L” to the user system
through the reset clip on the M38000T2-CPE. However, if the reset circuit on the user system 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 (if the MCU has it) or CNVss pins properly.
emulator cannot supply the power to the user system. Design you system so that the user system is
powered separately.
IMPORTANT
Check that target status LED (POWER) is ON.
Check that target status LED (CLOCK) is ON.
