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:

8 COMMAND7:

Display Control Command Table
Once written, the command identification code in the first byte is stored until the next first byte is written. However,
when the display character data write command (COMMAND1) is written, the LC74785/M locks into the display
character data write mode, and another first byte cannot be written.
When the CS1 pin is set high, the LC74785/M is set to the COMMAND0 (display memory write address setup mode)
state.
