8 / 23 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. 1 COMMAND0: Display memory (VRAM) write address setup command 2 COMMAND1: Display character data write command 3 COMMAND2: Vertical display start position and vertical character size setup command 4 COMMAND3: Horizontal display start position and horizontal character size setup command 5 COMMAND4: Display control setup command 6 COMMAND5: Display control setup command 7 COMMAND6: Synchronizing signal detection setup command 8 COMMAND7: Display control setup command 9 COMMAND8: Display control setup command 10 COMMAND9: Display control setup command 11 COMMAND10: Display control setup command Once written, a first byte command identification code is stored until the next first byte is written. However, when the display character data write command (COMMAND1) is written, the LC74788/M/JM locks into the display character data write mode, and another first byte cannot be written. When the CS pin is set high, the LC74788/M/JM is set to the COMMAND0 (display memory write address setup mode) state.
