9 / 35 page Display Control Commands Display control commands have an 8-bit format and are transferred using the serial input function. Commands consist of a command identification code in the first byte and command data in the following bytes. The following commands are supported. COMMAND0: Display memory (VRAM) write address setup command COMMAND1: Display character data write command COMMAND2: Vertical display start position and vertical character size setup command COMMAND3: Horizontal display start position and horizontal character size setup command COMMAND4: Display control setup command COMMAND5: Display control setup command COMMAND6: Synchronizing signal detection setup command COMMAND7 to COMMAND12 and COMMAND18: Display control setup commands COMMAND13 to COMMAND17: VPS/PDC control commands. These commands can only be written with the I2C bus (the SCL and SDA pins).

However, when the display character data write command (COMMAND1) is written, the LC74776/M locks into the display character data write mode, and another first byte cannot be written. When the CS pin is set high, the LC74776/M is set to the COMMAND0 (display memory write address setup mode) state. |
