(GND) -- 2 VSS P 3 VCC P Function Reserved Pin (Supporting Pin). The supporting pins can reduce the influences from stresses on the function pins. This pin must be connected to external ground. Ground of Logic Circuit This is a ground pin. It also acts as a reference for the logic pins. It must be connected to external ground Power Supply for OEL Panel This is the most positive supply pin of the chip. They must be connected to external source. Voltage Output High Level for COM Signal 4 VCOMH P 5 VLSS P This pin is the input pin for the voltage output high level for COM signals. A tantalum capacitor should be connected between this pin and VSS. Ground of Analog Circuit This is analog ground pin. It should be connected to VSS externally Host Data Input/Output Bus 6~13 D7~D0 I/O These pins are 8-bit bi-directional data bus to be connected to the microprocessors data bus. When serial mode is selected, D1 will be the serial data input SDIN and D0 will be the serial clock input SCLK. Unused pins must be connected to VSS except for D2 in serial mode. Read/Write Enable or Read 14 E/RD# I This pin is MCU interface input. When interfacing to a 68XX-series microprocessor, this pin will be used as the Enable (E) signal. Read/write operation is initiated when this pin is pulled high and the CS# is pulled low. When connecting to an 80XX-microprocessor, this pin receives the Read (RD#) signal. Data read operation is initiated when this pin is low and CS# is pulled low. When serial mode is selected, this pin must be connected to VSS. Read/Write Select or Write 15 R/W# I This pin is MCU interface input. When interfacing to a 68XX-series microprocessor, this pin will be used as Read/Write (R/W#) selection input. Pull this pin to “High” for read mode and pull it “Low” for write mode. When 80XX interface mode is selected, this pin will be the Write (WR#) input. Data write operation is initiated when this pin is pulled low and the CS# is pulled low. When serial mode is selected, this pin must be connected to VSS.
