Description

VDD

Power supply pin for logic.

VSS

Ground pin, connected to 0V

CSB

Chip select input pin.

RSTB

Hardware reset input pin

It determines whether the access is related to data or
command.

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.

RWR is not used 4-line SPI interface and should fix to “H” by VDD

ERD

C86	MPUType	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 falling edge of E signal.
L	8080 series	/RD	Read enable input pin. When /RD is “L”, D[7:0] are in output mode.

ERD is not used in 4-Line SPI interface and should fix to “H” by VDD

9~16

D0~D7

When using 8-bit parallel interface: (6800 or 8080 mode)
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

When using serial interface: 4-line SPI
D[0]=SCL: Serial clock input.
D[1]=SDA_IN: Serial data input.
D[2:3]=SDA_OUT: Serial data output.
D[1:3] must be connected together as SDA.
D[4:7]=(1,1,1,1): ID Pin. D[4:7] should fix to “H” or “L” by VDDH or VSSL.
ID[0:3] can be read 4-bit ID only for serial interface from D[4:7].

C86

C86 selects the microprocessor type in parallel interface mode.

PSB	C86	Selected Interface
“L”	“H”	Serial 4-Line SPI Interface
“H”	“L”	Parallel 8080 Series MPU Interface
“H”	“H”	Parallel 6800 Series MPU Interface

PSB

PSB selects the interface type: Serial or Parallel.
