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.

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 LC74789/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 LC74789/M/JM is set to the COMMAND0 (display memory write address setup mode)
state.
