2 Symbol Definition
D0-D17
BS0, BS1, BS2, BS3
logic setting, which is described in the following table. User can fix these pins by jumper (J2, J3).
Unlike BS0,BS1 which are controlled by hardware, BS2,BS3 is controlled by software command
0x36.
E/RD#
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#
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.
D/C#
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#
CS#
pulled low.
