The character LCD can be used in either 8-bit mode or 4-bit mode. In 8-bit mode, the commands, as well as the data, are directly sent using the 8 data bits DB0-DB7. In 4-bit mode only the higher 4 bits i.e. DB7-DB4 are used. So to send an 8-bit data or command, the higher 4 bits are sent first followed by the lower 4 bits.
