Display Control Commands
Display control commands are input in an 8-bit serial format. Commands consist of a command identification code in the
first byte and data in the second and following bytes. The following commands are supported.
Display Control Command Table
Once the command identification code in the first bite is written, it is stored internally until the first byte of the following
command is written. However, when the display character data write command (COMMAND1) is written, the system
becomes locked in display character data write mode, and the first byte cannot be overwritten.
When the CS pin is set high the command state is set to COMMAND0, i.e., display memory write address setting mode.
