ADV7194

Mode 1: Slave Option HSYNC, BLANK, FIELD

(Timing Register 0 TR0 = X X X X X 0 1 0)

In this mode the ADV7194 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 ADV7194

automatically blanks all normally blank lines as per CCIR-624. Mode 1 is illustrated in Figure 42 (NTSC) and Figure 43 (PAL).
