ADV7172/ADV7173
Mode 3: Master/Slave Option HSYNC, BLANK, FIELD
(Timing Register 0 TR0 = X X X X X 1 1 0 or X X X X X 1 1 1)
In this mode the ADV7172/ADV7173 accepts or generates horizontal SYNC and Odd/Even FIELD signals. A transition of the
FIELD input when HSYNC is high indicates a new frame, i.e., vertical retrace. The BLANK signal is optional. When the BLANK
input is disabled, the ADV7172/ADV7173 automatically blanks all normally blank lines as per CCIR-624. Mode 3 is illustrated in
Figure 34 (NTSC) and Figure 35 (PAL).
