COMMANDS & DATA
• Others: command (1 Byte) + data (1 Byte)
TM
• Transferring display data/displaying on LCD: command (1 Byte) + data (256 Bytes)
• Commands can be accepted only when all bits coincide; otherwise, they are not acknowledged
• Additional commands will not be received until the communication of commands (1 Byte) and data (256 or 1 Byte) is completed
• There is no time limit from the beginning to end of data receipt
• Commands may be executed consecutively (no need to wait between commands)
• Irregular commands or data are not recognized
• Initial status at power activation: LCD display off, LED off (brightness 1/20, color off)
