Pin功能定義
| PinSDA | Symbol | Level | Function |
|---|---|---|---|
| 1 | /CS1 | I | This is the chip select signal |
| 2 | /RES | I | When /RES is set to “L,” the settings are initialized. The reset operation is performed by the /RES signal level. |
| 3 | A0 | I | It determines whether the access is related to data or command. A0=“H” : Indicates that signals on D[7:0] are display data. A0=“L” : Indicates that signals on D[7:0] are command. |
| 4 | /WR, R/W | I | /WR, 8080 mode. R/W, 6800 mode. |
| 5 | /RD, E | I | /RD, 8080 mode. E, 6800 mode. |
| 6~13 | D0(SCL) D1(SDA) D2~D7 | I/O | When using serial interface: 4-line SPI,3-line SPI or I2C serial interface D[0]=SCL: Serial clock input. ID[0:3] can be read 4-bit ID only for serial interface from D[4:7]. |
| 14 | VDD | 3.3V | Power supply for logic |
| 15 | VSS | 0V | Power supply for logic GND |
| 16~18 | NC | - | Not used. |
| 19 | V0 | O | V0 is the LCD driving voltage for common circuits at negative frame. |
| 20 | XV0 | O | XV0 is the LCD driving voltage for common circuits at positive frame. |
| 21~24 | NC | - | Not used. |
| 25 | VG | O | VG is the LCD driving voltage for segment circuits. |
| 26~30 | NC | - | Not used. |
| 31 | C86 | I | C86 selects the microprocessor type in parallel interface mode. |
| 32 | PSB | I | PSB selects the interface type: Serial or Parallel. |
| 33 | SI2 | I | SI2 selects the interface type: I2C serial interface or not |
| 34 | NC | - | Not used. |
