TABLE 15. TIMING I/O REGISTER #1
SUB ADDRESS = 04H
DESCRIPTION
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
negates 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
