| 6 | __ CS |
This pad is the chip select input. When /CS = “L”, then the chip select becomes active, and data/command I/O is enabled. | ||||||||||||
| 7 | ___ 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. | ||||||||||||
| 8 | A0 | This is the Data/Command control pad that determines whether the data bits are data or a command. In I2C interface, this pad serves as SA0 to distinguish the different address of OLED driver. |
