Interface Definition
| Pin No. | Symbol | Level | Description |
| 1 | CS1 | H/L | Chip select signal |
| 2 | RST | H/L | Chip reset signal |
| 3 | A0 | H/L | Register selection input H : Indicate that D0 to D7 are display data. L:Indicate that D0 to D7 are control data |
| 4 | WR(R/W) | H/L | 8080 series: Write signal 6800 series: Read or Write signal |
| 5 | RD(E) | H/L | 8080 series: Read signal 6800 series: Enable signal |
| 6–13 | D0-D5 D6(SCL) D7(SI) | H/L | This is an 8-bit bi-directional data bus that connects to an 8-bit or 16-bit standard MPU data bus. When the serial interface (SPI-4) is selected (P/S = “L”) : D7 : serial data input (SI) ; D6 : the serial clock input (SCL). D0 to D5 should be connected to VDD or floating. |
