Interface Pin Function
| No. | Symbol | Function |
|---|---|---|
| 1 | GND | Ground. |
| 2 | VCC | Power supply pin for logic. |
| 3 | D0 | When the serial interface is selected, then D0 serves as the serial clock input pad (SCL) and D1 serves as the serial data input pad (SI). |
| 4 | D1 | |
| 5 | RES# | This pin is reset signal input. When the pin is pulled LOW, initialization of the chip is executed. Keep this pin HIGH (i.e. connect to VDD) during normal operation. |
| 6 | D/C# | This is the Data/Command control pad that determines whether the data bits are data or a command. D/C = "H": the inputs at D0 and D1 are treated as display data. D/C = "L": the inputs at D0 and D1 are transferred to the command registers. |
| 7 | CS# | This pin is the chip select input. (active LOW) |
