This bit is ignored unless BLANK is configured to be an output.
0 = Data for the first active pixel of the scan line must arrive the CLK cycle after the encoder
negates BLANK.
1 = Data for the first active pixel of the scan line must arrive immediately after the encoder ne-
gates BLANK.
0 = BLANK is an input
1 = BLANK is an output
0 = Active low (low during blanking)
1 = Active high (high during blanking)
0 = HSYNC and VSYNC are inputs
1 = HSYNC and VSYNC are outputs
0 = Active low (low during horizontal sync)
1 = Active high (high during horizontal sync)
0 = Active low (low during vertical sync)
1 = Active high (high during vertical sync)
0 = Active low (low during odd fields)
1 = Active high (high during odd fields)
0 = Inputs are sampled when CLK is low (see Table 2).
1 = Inputs are sampled when CLK is high.
0 = CLK is an input
1 = CLK is an output
This bit must be set to “0” during BT.656 input mode.
0 = Rectangular (BT.601) pixels
1 = Square pixels
Selects the source of the color subcarrier NCO phase increment value.
00 = Internal (fixed) data.
01 = Reserved
10 = BT.656 RTCI ancillary data
11 = I
