In this mode the ADV7175A/ADV7176A 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. T he BLANK signal is optional. When the BLANK input is disabled
the ADV7175A/ADV7176A automatically blanks all normally blank lines. Mode 1 is illustrated in Figure 18 (NT SC) and Fig-
ure 19 (PAL).
