44.6.5.3 4:2:2 Semiplanar Mode Frame Buffer Memory Mapping
44.6.5.4 4:2:2 Planar Mode Frame Buffer Memory Mapping
44.6.5.5 4:2:0 Planar Mode Frame Buffer Memory Mapping
In Planar Mode, the three video components Y, Cr and Cb are split into 3 memory areas and stored in a raster-scan
order. These three memory planes are contiguous and always aligned on a 32-bit boundary.
