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).

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 LC74775/M locks into the display character data
write mode, and another first byte cannot be written.
When the CS pin is set high, the LC74775/M is set to the COMMAND0 (display memory write address setup mode) state.
