| Pin | Symbole | Description |
|---|---|---|
| 1 | CSB | Chip select input pin.Interface access is enabled when CSB is “L”,When CSB is non-active(CSB=”H”),D[7:0] pins are high impedance. |
| 2 | RSTB | Hardware reset input pin. When RSTB is “L”, interna initialization is executed and the internal registers will be initialized. |
| 3 | A0 | It determines whether the access is related to data or command. A0=“H” : Indicates that signals on D[7:0] are display data. A0=“L” : Indicates that signals on D[7:0] are command |
| 4 | RWR | Read/Write execution control pin. When PSB is “H”, RWR is not used in serial interface and should fix to “H” by VDD1 or VDDH. |
| 5 | ERD | Read/Write execution control pin. When PSB is “H”, ERD is not used in serial interface and should fix to “H” by VDD1 or VDDH. |
| 6 | D0 | When using 8-bit parallel interface: (6800 or 8080 mode) 8-bit bi-directional data bus. Connect to the data bus of 8-bit microprocessor. When CSB is non-active (CSB=“H”), D[7:0] pins are high impedance. |
