X is the read/write control bit; X = logic 0 is order to write; X = logic 1 is order to read, no subaddressing with read.
If more than 1 byte DATA is transmitted, then auto-increment of the subaddress is performed.

Cb/Cr data at MP are two’s complement.
Cb/Cr data at MP are straight binary. Default after reset.
Y data at MP are two’s complement.
Y data at MP are straight binary. Default after reset.
Cb/Cr data input to VP or DP are two’s complement. Default after reset.
Cb/Cr data input to VP or DP are straight binary.
Y data input to VP are two’s complement. Default after reset.
Y data input to VP are straight binary.
Selects YUV 422 format on VP (8 lines Y) and DP (8 lines multiplexed Cb/Cr).
Selects CCIR 656 compatible format on VP (8 lines Cb, Y, Cr). Default after reset.
Data from input ports are encoded. Default after reset.
Colour bar with programmable colours (entries of OSD_LUTs) is encoded.
The LUTs are read in upward order from index 0 to index 7.
