Mode 1: Master Option HSYNC , BLANK , FIELD
(Timing Register 0 TR0 = X X X X X 0 1 1)
In this mode, the ADV7174/ADV7179 can generate horizontal
SYNC and odd/even FIELD signals. A transition of the FIELD
input when HSYNC is low indicates a new frame, i.e., vertical
retrace. The BLANK signal is optional. When the BLANK input
