Note 1: The data order is as follows, MSB=D7, LSB=D0 and picture data is MSB=Bit 5, LSB=Bit 0 for Green and MSB=Bit 4, LSB=Bit 0 for
Red and Blue data.
Note 2: 2-times transfer is used to transmit 1 pixel data with the 16-bit color depth information.
Note 3: ‘-‘ = Don't care - Can be set to '0' or '1'
