2 Symbol Definition

D0-D7：These pins are 8-bit bi-directional data bus to be connected to the MCU’s data bus.

I/S#：This is a serial interface selection input pin. When it is pulled High and P/S# Pulled Low, I2C

interface is selected (J1).

PS#：This pin is a parallel interface selection input pin. . When it is pulled High, parallel interface mode is selected. When this pin and I/S# pin is pulled Low, serial interface is selected (J2).

Note: Read Data operation is only available in parallel mode.

CMPU：This pin is MCU parallel interface selection input. When the pin is pulled High, 6800 serial interface is selected and when the pin is pulled Low, 8080 serial interface is selected(P/S# pulled

Low). The setting of this pin is ignored, but must be connected to a known logic (either High or Low) (J3).

CCL：the pin is internal clock enable. When this pin is pulled High, internal clock is enabled. The internal clock is disabled when it is pulled Low. An external clock source must be connected to CL pin

for normal operation. (J4).

M/S#：This pin is the select input. This pin must be pulled High, the chip function is as master (J5).

E/RD#：This pin is MCU interface input. When interfacing to a 6800-series microprocessor, this pin

is used as the Enable (E) signal. Read/write operation is initiated when this pin is pulled high and the chip is selected.

When connecting to an 8080-microprocessor, this pin receives the Read (RD) signal. Data read operation is initiated when this pin is pulled low and the chip is selected. When serial interface is selected, this pin E(RD) must be connected to VSS.

R/W#：This pin is MCU interface input. When interfacing to a 6800-series microprocessor, this pin is used as Read/Write (R/W) selection input. Read mode will be carried out when this pin is pulled high

and write mode when low.

When 8080 interface mode is selected, this pin is the Write (WR) input. Data write operation is initiated when this pin is pulled low and the chip is selected. When serial interface is selected, this pin R/W must be connected to VSS.

RS#：This pin is Data/Command control pin. When the pin is pulled high, the data at D0-D7 is treated as display data. When the pin is pulled low, the data at D0-D8 is transferred to the command

register. For detail relationship to MCU interface signals, please refer to the timing characteristics diagrams at following pages and datasheet.

RES#：This pin is reset signal input. When the pin is low, initialization of the chip is executed.

CS#：This pin is the chip select input. The chip is enabled for MCU communication only when CS is pulled low.

VCC：This is the most positive voltage supply pin of the chip.

VDD3.3V：Power supply pin for logic operation of the driver.
