Power supply and power supply for interface logic level.
Internal VDD regulator selection pin in 5V I/O application
mode.
When this pin is pulled HIGH, internal VDD regulator isenabled (5V I/O application).
When this pin is pulled LOW, internal VDD regulator isdisabled (Low voltage I/O application).
This pin is Data/Command control pin connecting to theMCU.
When the pin is pulled HIGH, the data at D[7:0] will beinterpreted as data.
When the pin is pulled LOW, the data at D[7:0] will betransferred 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.
This pin is read / write control input pin connecting to theMCU 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 theWrite (WR#) input. Data write operation is initiated when thispin is pulled LOW and the chip is selected.
When serial or I2C interface is selected, this pin must beconnected to VSS.
This pin is MCU interface input.
When 6800 interface mode is selected, this pin will be usedas 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 theRead (RD#) signal. Read operation is initiated when this pinis pulled LOW and the chip is selected.
When serial or I2C interface is selected, this pin must beconnected to VSS.

D7These pins are bi-directional data bus connecting to theMCU data bus.
Unused pins are recommended to tie LOW.

I/O

When serial interface mode is selected, D0 will be the serialclock input: SCLK; D1 will be the serial data input: SID andD2 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 theserial clock input, SCL.

This pin is the chip select input connecting to the MCU.
The chip is enabled for MCU communication only when CS#is pulled LOW (active LOW).
In I2C mode, this pin must be connected to VSS.
This pin is reset signal input.
When the pin is pulled LOW, initialization of the chip isexecuted.
Keep this pin pull HIGH during normal operation.
