19.4.5 Input Display Data Format
The following format is used for input color data used in display.
• 8 bit/pixel
A color palette index is used. The color palette is used to convert and display image data into
RGB data with 6 bits for each RGB color (RGB666).
The arrangement of data in memory is as follows.
A+3 A+2 A+1 A A A+1 A+2 A+3
31 23 15 7 0 31 23 15 7 0
Address A Index 3 Index 2 Index 1 Index 0 Address A Index 0 Index 1 Index 2 Index 3
Address A+4 Index 7 Index 6 Index 5 Index 4 Address A+4 Index 4 Index 5 Index 6 Index 7
Address A+8 Index 11 Index 10 Index 9 Index 8 Address A+8 Index 8 Index 9 Index 10 Index 11
Little endian Big endian
• 16 bit/pixel: RGB
The RGB levels are represented using 5 bits for R, 6 bits for G, and 5 bits for B (RGB565).
