3.3 Setting Power Supply Voltage of Target Interface
In the IE system, emulation is possible with a voltage of the same level as the power supply voltage of the target
system.
When the target system is not connected, the IE system automatically operates with the emulator's internal power
supply (3.9 V). When debugging with a voltage that is the same level as that of the target system, supply the same
voltage (2.7 to 3.6 V: same as that of the device) as that of the target system to the 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).

Before connecting the board and the target system power supply voltage, turn off the power to
the IE-78K0S-NS or IE-78K0S-NS-A.
