D7~D0

8-bit bi-directional data bus. Connect to the data bus of 8-bit
microprocessor. When CSB is non-active (CSB=“H”),
D[7:0] pins are high impedance.

ERD

C86	MPU Type	ERD	Description
H	6800 series	E	Read/Write control input pin. R/W=”H”: When E is “H”, D[7:0] are in output mode. R/W=”L”: Signals on D[7:0] are latched at the failing edge of E signal.
L	8080 series	/RD	Read enable input pin. When /RD is “L”, D[7:0] are in output mode.

RWR

C86	MPU Type	RWR	Description
H	6800 series	R/W	Read/Write control input pin. R/W=”H”: read. R/W=”L”: write.
L	8080 series	/WR	Write enable input pin. Signals on D[7:0] will be latched at the rising edge of /WR signal.

It determines whether the access is related to data or command

RSTB

Hardware reset input pin

CSB

Chip select input pin.
