Notes
1. 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.
2. 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 is two’s complement.
Y data is straight binary. Default after reset.
Y, Cb and Cr for RGB dematrix is active. Default after reset.
Y, Cb and Cr for RGB dematrix is bypassed.
Horizontal and vertical trigger is taken from RCV2 and RCV1 respectively. Default after reset.
Horizontal and vertical trigger is decoded out of “CCIR 656” compatible data at MP port.
Output of CVBS and RGB signals. Default after reset.
Output of Y, C, and CVBS, CVBS signals.
Data from input ports is encoded. Default after reset.
Colour bar with fixed colours is encoded. The LUTs are read in upward order from
index 0 to index 7.
