M38000T2-CPE User’s Manual
2.6.5 Reset Circuit of the User System
To debug with the M38000T2-CPE, use either an open-drain type reset IC or a CR reset circuit. The recommended pull-up
value is about 10 kΩ. The MCU can be reset by outputting "L" to the target through the reset clip on the M38000T2-CPE.
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.
Figure 2.9 shows the internal reset circuit connection diagram of the emulator.

2.6.6 Checking the Connections
Before turning the power ON, check the connection of the host machine, interface cable, compact emulator and user system.
2.6.7 Turning ON/OFF the Power
Turn ON/OFF the power of the emulator and user system as simultaneously as possible.
Do not leave either the emulator or user 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 for about 10 seconds.
2.6.8 Power Supply to the User System
This emulator cannot supply the power to the user system. Therefore design your system so that the user system is powered
separately.
The voltage of the user system should be 1.8 V ≤ Vcc ≤ 5.0 V. Do not change the voltage of the user system after turning on
the power.

Notes on Power Supply:
• As this emulator cannot supply power to the user system, provide the user system with a separate power supply.
• This emulator consumes max. 50 mA of electrical current from user system. Therefore, set the power supply of
• 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 user system power supply voltage after power has been activated.
