Display Control Commands
The display control commands have a serial input format with 8-bit units. A command consists of a command identifier
code in the first byte and data in the second and subsequent bytes. There are eight commands as listed below.
x COMMAND0: Display memory (VRAM) write address setup command
COMMAND1: Display character data write command
z 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: Synchronization signal detection setup command
COMMAND7: Display control setup command
Display Control Command Table
Once written, the command identifier 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 LC74784/M locks into the display character
data write mode, and another first byte cannot be written.
When a high level is input to the CS pin, the LC74784/M is set to COMMAND0 (display memory write address setup
mode).
