功能說明

VDD

Power supply pin for logic.

VSS

Ground pin, connected to 0V

/CS1

Chip select input pin. Interface access is enabled when CS1B is “L” and CB2 is “H”. When chip is on-active (CS1B=“H” or CS2=”L”), D[7:0] pins are high impedance.

CS2

/RES

Hardware reset input pin. When RSTB is “L”, internal initialization is executed and the internal registers will be initialized.

It determines whether the access is related to data or command.
A0=“H”: Indicates that signals on D[7:0] are display data.
A0=“L”: Indicates that signals on D[7:0] are command.

R/W

Read/Write execution control pin. When PSB is “H”,
RWR is not used in serial interface and should fix to “H” by VDD.

C86	MPU Type	RWR	功能說明
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.

Read/Write execution control pin. When PSB is “H”,

C86	MPU Type	ERD	功能說明
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 serial interface and should fix to “H” by VDD.

9-16

D0-D7

I/O

Data bus line

C86

C86 selects the microprocessor type in parallel interface mode.

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

Please refer to “APPLICATION NOTES” and “Microprocessor Interface” (Section 6) for detailed connection of the selected interface.

P/S

PSB selects the interface type: Serial or Parallel.
