Mode 1: Slave Option HSYNC, BLANK, FIELD
Timing Register 0 TR0 = X X X X X 0 1 0
In this mode, the ADV7177/ADV7178 accepts horizontal SYNC and odd/even FIELD signals. A transition of the FIELD input when
HSYNC is low indicates a new frame, that is, vertical retrace. The BLANK signal is optional. When the BLANK input is disabled, the
ADV7177/ADV7178 automatically blank all normally blank lines. Mode 1 is illustrated in Figure 18 (NTSC) and Figure 19 (PAL).
