Description

1

 CSB

H/L

Chip select input pin. Interface access is enabled when CSB is “L”.

2

RSTB

H/L

Hardware reset input pin. When RSTB is “L”, internal initialization is executed and the internal registers will be initialized.

3

A0

H/L

It determines whether the data bits are data or command.          

 A0 = “H”: Indicates that D0 to D7 are display data.                

A0 = “L”: Indicates that D0 to D7 are control data.

4

/WR_R/W

 

8080 series MPU Type:Write enable input pin.  

Signals on D[7:0] will be latched at the rising edge of /WR signal.  

6800 series MPU Type: 

Read/Write control input pin.  

R/W=“H”: read. R/W=“L”: write.                             

5

/RD_E

 

8080 series MPU Type: 

Read enable input pin.  

When /RD is “L”, D[7:0] are in output mode 

6800 series MPU Type:Read/Write control input pin.    

R/W=”H“: When E is “H”, D[7:0] are in output mode.   

R/W=”L“: Signals on D[7:0] are latched at the falling edge of E signal.

D0

H/L

When using 8-bit parallel interface: (6800 or 8080 mode) 

8-bit bi-directional data bus.When CSB is non-active  (CSB=“H”), D[7:0] pins are high impedance. 

 When using serial interface: 4-LINE 

D7=SDA : Serial data input.  

D6=SCL : Serial clock input. 

D[5:0] are not used and should connect to “H” by VDD. 

When CSB is non-active (CSB=“H”), D[7:0] pins are high impedance.
