D / C#

I

This pin is data / command control pin connecting to the MCU. When the pin is pulled “high”, the

data at D [7:0] will be interpreted as data.

When the pin is pulled “low”, the data at D [7:0] will be transferred to a command register.

In I2C mode, this pin acts as SA0 for slave address selection. When serial interface is selected, this

pin must be connected to VSS.

16

R / W#

(WR#)

I

This pin is read / write control input pin connecting to the MCU interface.

When 6800 interface mode is selected, this pin will be 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 will be the write (WR#) input. Data write operation is

initiated when this pin is pulled “low” and the chip is selected.

When serial or I2C interface is selected, this pin must be connected to VSS.

17

E (RD#)

I

This pin is MCU interface input.

When 6800 interface mode is selected, this pin will be used as the enable (E) signal. Read / write

operation is initiated when this pin is pulled “high” and the chip is selected.

When 8080 interface mode is selected, this pin receives the read (RD#) signal. Read operation is

initiated when this pin is pulled “low” and the chip is selected.

When serial or I2C interface is selected, this pin must be connected to VSS.

18

D0

I/O

These pins are bi-directional data bus connecting to the MCU data bus.

Unused pins are recommended to tie “low”.



When serial interface mode is selected, D0 will be the serial clock input: SCLK; D1 will be the serial

data input: SID and D2 will be the serial data output: SOD.

When I2C mode is selected, D2, D1 should be tied together and serve as SDAout, SDAin in

application and D0 is the serial clock input, SCL.

IREF

I

This pin is the segment output current reference pin. IREF is supplied externally. A resistor should

be connected between this pin and VSS to maintain current of around 15 μA

27

ROM0

I

These pins are used to select character ROM; select appropriate logic setting as described in the

following table. ROM1 and ROM0 are pin select as shown in below table.
