DESCRIPTION
0 data from input ports is encoded
1 colour bar with fixed colours is encoded
0 horizontal and vertical trigger is taken from FSVGC or both VSVGC and HSVGC; default
after reset
1 horizontal and vertical trigger is decoded out of “ITU-R BT.656” compatible data at PD port
0 Y-C_B-C_R to RGB dematrix is active; default after reset
1 Y-C_B-C_R to RGB dematrix is bypassed
0 pin 26 provides a horizontal sync for non-interlaced VGA components output (at PIXCLK)
1 pin 26 provides a composite sync for interlaced components output (at XTAL clock)
0 input luminance data is twos complement from PD input port
1 input luminance data is straight binary from PD input port; default after reset
0 input colour difference data is twos complement from PD input port
1 input colour difference data is straight binary from PD input port; default after reset
