3.3 Power Supply Voltage Setting of Target Interface
The IE system allows emulation at the same voltage level as that of the target system.
When the target system is not connected, the system automatically operates on the internal power supply (3 V) of
the emulator. When debugging at the same voltage level as that of the target system, supply the TM1 terminal pin of
the IE-789835-NS-EM1 with the same voltage as that of the target system (the same applies when the voltage is 3
V).
For how to select the operating power supply, refer to the ID78K Series Ver. 2.30 or Later Operation (Windows
Based) User’s Manual (U15185E) .

Maximum current consumption of TM1 3 V: Approximately 100 mA
