Mode 2: Master Option HSYNC, VSYNC, BLANK
(Timing Register 0 TR0 = X X X X X 1 0 1)
In this mode, the ADV7175A/ADV7176A 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 ADV7175A/ADV7176A automatically blanks
all normally blank lines as per CCIR-624. Mode 2 is illustrated in Figure 21 (NTSC) and Figure 22 (PAL). Figure 23 illus-
trates 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.
