Interface Pin Definition (Hardware connection)
| Pin | Symbol | Descriptions |
| 1 | GND | Ground of Logic Circuit |
| 2 | VDD | Power Supply for Logic |
| 3 | SCK | Serial clock input. |
| 4 | SDA | Serial data input. |
| 5 | RST | This pin is reset signal input. When the pin is low, initialization of the chip is executed. Keep this pin pull high during normal operation. |
| 6 | DC | This pin is Data/Command control pin. When the pin is pulled high and serial interface mode is selected, the data at SDIN will be interpreted as data. When it is pulled low, the data at SDIN will be transferred to the command register. |
| 7 | CS | Chip Select. Chip is selected when CS0 = “L” . |
