•Precaution when designing

When evaluation MCU on the user system is operated in the state that the emulator is not connected, should be treated as follow each input terminal of evaluation MCU connected with the emulator interface on the user system.

Therefore, note that the switch circuit etc, might become necessary in the user system when you design.

The terminal processing in each emulator interface is shown as follows.

Pin treatment of emulator interface (DSU-3)

Evaluation MCU terminal name			Pin treatment
RST			To be connected the RST terminal with the reset output circuit in the
			user system.
Others			To open.
Emulator interface wiring regulations
Signal line name			Wiring regulations
ICLK	• The total wiring length of each signal (From evaluation MCU pin to the
ICS2 to ICS0		emulator interface connector pin) is made within 50 mm.
ICD3 to ICD0	• The difference of the total wiring length of each signal makes within 2 cm
BREAKI		and the total wiring length of ICLK is the shortest.
	• Wire the pattern with capacity more than the ratings current.
UVCC	• Each power supply and GND may cause a short-circuit or reverse connec-
		tion in between by a wrong connection of a probe. Insert a protection circuit
		such as a fuse into each power supply pattern to safeguard it.
GND	• Connect directly with a power supply system pattern such as grandopran.
