Setting Power Supply Voltage Of Target Interface - NEC IE-789801-NS-EM1 User Manual

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 (5 V).
When debugging with a voltage that is the same level as that of the target system, supply the same voltage as that
of the target system to the TM1 terminal pin of the IE-789801-NS-EM1 (the same applies when the voltage is 5 V).
Set the target voltage to between 4.0 and 5.0 V.
• Maximum current consumption of TM1
4.0 to 5.0 V: Approximately 100 mA
