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 are two’s complement.
Cb/Cr data are straight binary. Default after reset.
Y data are two’s complement.
Y data are straight binary. Default after reset.
Selects Cb, Y, Cr, Y on 8 lines on MP port (“CCIR 656”compatible). Default after
reset.
Selects Cb, Cr on DP port and Y on MP port.
OVL keying enabled for Y, C and CVBS outputs. Default after reset.
OVL keying disabled for Y, C and CVBS outputs.
Data from input ports are encoded. Default after reset.
Colour bar with programmable colours (entries of OVL_LUTs) is encoded.
The LUTs are read in upward order from index 0 to index 7.
