4	Data or Command select. DATA is “H” , COMMAND is “L”	A0
5	While connected to 8080 series MPU,this pin is treated as the” /WR”	/WR(R/W)
	signal of the 8080 MPU and is LOW-active.
	While connected to 6800 series MPU,this pin is treated as the”RW”
	signal of the 6800 MPU and decides the access
	type:WHEN RW=”H”: Read.WHEN RW=”L”: Write.

6	While connected to 8080 series MPU,	/RD(E)
	this pin is treated as the “/RD” signal of the 8080 MPU and is LOW-active.
	While connected to 6800 series MPU,this pin is treated as the “E”
	signal of the 6800 MPU and is HIGH-active.
