Mode 2: Master Option HSYNC , VSYNC , BLANK
(Timing Register 0 TR0 = X X X X X 1 0 1)
In this mode, the ADV7174/ADV7179 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
