of the target system to the TP1 terminal pin of the IE-789456-NS-EM1 (the same applies when the voltage is 5 V).
Based User’s Manual (U15185E).
Caution
Remark The V
In the IE system, emulation is possible with a voltage of the same level as the power supply voltage of the target
When the target system is not connected, the IE system automatically operates with the emulator’s internal power
When debugging with a voltage that is the same level as that of the target system, supply the same voltage as that
Set the target voltage to between 1.8 and 5.0 V.
For how to select the operating power supply, refer to the ID78K Series Ver.2.30 or Later Operation Windows-
