(Timing Register 0 TR0 = X X X X X 0 1 0)
In this mode the ADV7190/ADV7191 accepts 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 is disabled the ADV7190/ADV7191 automatically blanks all normally blank lines as per CCIR-624. Mode 1 is illustrated
