Colour look-up tables (CLUTs)
The CLUTs consist of RAM tables. The RAM tables can be loaded with X = 0 to 255 in accordance with equation 1 for
the signals R, G and B. Gamma-correction (pre-distortion) by the following equation:
Y = NINT (b + a
×
X1
1/g
); Y(X
≤
16) = 16; Y(X
≥
235) = 235 (equation 1) with g = 2.2:
b = 16

;
The RAM tables are loaded via MPU-bus or via I

C-bus (Table 17).
