•

V

DD

pin

When the target system is not connected, the internal power supply voltage (5 V) of the IE-789026-NS-EM1 is

supplied to the emulation CPU. When the target system is connected, power is supplied via the voltage

supply pin (TP1). The V

DD

pin of the target system is only used to control the LED (TV

CC

) in the IE-789026-

NS-EM1 that monitors the input of the target system's power supply.

•

V

SS

pin

The V

SS

pin is connected to GND in the IE-789026-NS-EM1.

•

V

PP

/IC pin

The V

PP

and IC pins are not used in the IE-789026-NS-EM1.

•

X2 pin

The X2 pin is not used in the IE-789026-NS-EM1.
