Mode 2: Master Option HSYNC, VSYNC, BLANK
(Timing Register 0 TR0 = X X X X X 1 0 1)
In this mode the ADV7170/ADV7171 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 ADV7170/ADV7171 automatically blank all normally blank lines as
per CCIR-624. Mode 2 is shown in
(NTSC) and
(PAL).
