ADV7177/ADV7178
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 ADV7177/ADV7178 accept or generate horizontal SYNC and odd/even field signals. A transition of the field input
when HSYNC is high indicates a new frame, that is, vertical retrace. The BLANK signal is optional. When the BLANK input is disabled,
