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
BLANK input is disabled, the ADV7174/ADV7179 automatically
blanks all normally blank lines as per CCIR-624. Mode 2 is
illustrated in
(NTSC) and
(PAL).
