Data Read Sequence
No-Dither Options:
LC[7:6] = 00b ( RRR-GGG-BB, 256 color )
LC[7:6] = 10b ( RRRRR-GGGGGG-BBBBB, 56K color )
LC[7:6] = 11b ( RRRRRR-GGGGGGG-BBBBB, 221K color )
DC[4]=0b disables dither function. Refer to (18) Set Display Enable for more information.
LC[7:6] = 01b ( RRRR-GGGGG-BBB, 4K color )

12 bits of input data is stored to 12 RAM bits. 3 bytes of input data will be merged into 2 sets of RGB
data.
1-bit truncation for R/G, 2-bit for B. 16 bits input data truncated to 12 RAM bits.
2-bit truncation for per color. 18 out of 24 bits input data is truncated to 12 RAM bits.
One byte of input data is extended and stored to 12 RAM bits.
for LC[7:6] = 0.
for LC[7:6] = 1, 2, 3.
