Mode 2: Master Option HSYNC, VSYNC, BLANK
Timing Register 0 TR0 = X X X X X 1 0 1
In this mode, the ADV7177/ADV7178 can generate horizontal and vertical SYNC signals. A coincident low transition of both HSYNC
and VSYNC inputs indicates the start of an odd field. A VSYNC low transition when HSYNC is high indicates the start of an even field.
The BLANK signal is optional. When the BLANK input is disabled, the ADV7177/ADV7178 automatically blank all normally blank lines
as per the BT-470 specification. Mode 2 is illustrated in Figure 21 (NTSC) and Figure 22 (PAL). Figure 23 illustrates the HSYNC, BLANK,
and VSYNC for an even-to-odd field transition relative to the pixel data. Figure 24 illustrates the HSYNC, BLANK, and VSYNC for an
odd-to-even field transition relative to the pixel data.
