An automatic address increment function is built in. To write multidigit display character codes,
issue the Address Set command. To transfer the second and later digit display character codes,
the first byte (operation code) of the Character Code command is not required. Input the second
byte.
When this command is executed, 8-bit data for the second byte and later bytes, which is provided
before the CS pin is turned High, is all treated as display character data.
