Gamma
The Gamma block performs an 8-bit to 10-bit lookup table on the 3 x 8 bits (R, G, B) color data
coming from the LCD Scaler. The lookup table (LUT RAM) contains the corresponding 10-bit output
corrected color for each 8-bit input color.
The RAMs are individually programmable (read and write) using I2C access. The memory map is
as follows:
Even addresses are the 8-bit LSBs of the 10-bit gamma value. Odd addresses are the 2 MSBs.
