Mode 2: Master Option HSYNC, VSYNC, BLANK
(Timing Register 0 TR0 = X X X X X 1 0 1)
In this mode the ADV7190/ADV7191 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 ADV7190/ADV7191 automatically blanks
all normally blank lines as per CCIR-624. Mode 2 is illustrated in Figure 40 (NTSC) and Figure 41 (PAL). Figure 42 illustrates
the HSYNC, BLANK and VSYNC for an even-to-odd field transition relative to the pixel data. Figure 43 illustrates the HSYNC,
BLANK and VSYNC for an odd-to-even field transition relative to the pixel data.
