Mode 2: Master Option HSYNC, VSYNC, BLANK
(Timing Register 0 TR0 = X X X X X 1 0 1)
In this mode the ADV7172/ADV7173 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 ADV7172/ADV7173 automatically blanks all
normally blank lines as per CCIR-624. Mode 2 is illustrated in Figure 30 (NTSC) and Figure 31 (PAL). Figure 32 illustrates the
HSYNC, BLANK, and VSYNC for an even-to-odd field transition relative to the pixel data. Figure 33 illustrates the HSYNC,
BLANK, and VSYNC for an odd-to-even field transition relative to the pixel data.
