| 1 | GND | Ground |
| 2 | VCC | Power supply input |
| 3 | D0 | The serial clock input |
| 4 | D1 | The serial data input |
| 5 | RES# | This is a reset signal input pad. When RES# is set to "L", the settings are initialized. The reset operation is performed by the RES# signal level. |
| 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 input at D1 is treated as display data D/C# ="L"：the input at D1 is transferred to the command registers. |
| 7 | CS# | This pad is the chip select input. When CS# ="L", then the chip select becomes active, and data/command I/O is enabled. |
