2.4 Output Signal Processing
At the memory output the chrominance components are demultiplexed and linearly
interpolated to the luminance sample rate.
Different output formats are available: luminance signal Y with inverted or non-inverted
chrominance signals (B-Y), (R-Y) or RGB. For the RGB conversion 3 matrices are
integrated:

Matrix selection is done by pin SYS or I²C Bus. The matrices are designed for the
following input voltages (100 % white, 75 % color saturation):
