IT66121FN
The IT66121 supports another IO mapping method of YCbCr 4:2:2 formats which we call
Non-sequential IO Mode. The only difference between these two modes is the Y/Cb/Cr data mapping
sequence of the IO pin. The following tables show the different mappings of these two modes.
Non-sequential IO mode of 16/20/24-bit YCbCr422
