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.
