In 24-bit mode, the deserializer can receive only up to 18-bit color (6 bits per color). The LUT tables can translate from 6-bit to 6-bit, using the first 64 locations (0x00 to 0x3F). Program the MSB 2 bits of each LUT value to 00. Alternatively, pro- gram full 8-bit values to each LUT for 6-bit to 8-bit color translation. Recommended LUT Program Procedure 1) Write LUTPROG = 1 to register 0x7C. Keep BLULUTEN = 0, GRNLUTEN = 0, REDLUTEN = 0 (write 0x08 to register 0x7C). 2) Write contents of red LUT with a single write packet. For 24-bit RGB, use 0x7D as register address and 0x00 as number of bytes (UART only) and write 256 bytes. For 18-bit RGB, use 0x7D as register address and 0x40 as number of bytes (UART only) and write 64 bytes. (Optional: Multiple write packets can be used if LUTADDR is set before each LUT write packet.) 3) Read contents of red LUT and verify that they are correct. Use the same register address and number of bytes used in the previous step. 4) Repeat steps 2 and 3 for the green LUT, using 0x7E as the register address. 5) Repeat steps 2 and 3 for the blue LUT, using 0x7F as the register address. 6a) To finish the program and verify routine, without enabling the LUT color translation, write LUTPROG = 0 (write 0x00 to register 0x7C). 6b) To finish the program and verify routine, and start LUT color translation, write LUTPROG = 0, BLULUTEN = 1, GRNLUTEN = 1, REDLUTEN = 1 (write 0x07 to register 0x7C).
