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:

I2C address 0x1000 to 0x11FF: Red RAM

I2C address 0x1200 to 0x13FF: Green RAM

I2C address 0x1400 to 0x15FF: Blue RAM

Even addresses are the 8-bit LSBs of the 10-bit gamma value. Odd addresses are the 2 MSBs.
