The power supply of the emulation CPU operates on the internal power supply voltage (5 V) when the
target system is not connected, and on the voltage supplied from the low voltage supply pin (TM1) (LV
when the target system is connected. In the IE-789468-NS-EM1, the V
exclusively used for controlling LED1 (USER VDD), which monitors whether the power of the target system
is on.
