LVDS Interface
Different Color Mapping options exists. Please see National
Application Notes 1127 and AN-1163 for details. A careful
review of Color Mapping information is recommended as
Note 16: For a 48-bit dual pixel application - LSB (Less Significant Bit) = R16,G16,B16,R26,G26,B26 and MSB (Most Significant Bit) = R15,G15,B15,R25,G25,B25.
Note 17: For a 36-bit dual pixel application - LSB (Less Significant Bit) = R10,G10,B10,R20,G20,B20 and MSB (Most Significant Bit) = R15,G15,B15,R25,G25,B25.
