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 accepts or generates Horizontal SYNC and Odd/Even FIELD signals. A transition of the
FIELD input when
HSYNC
is high indicates a new frame, i.e., vertical retrace. The
BLANK
signal is optional. When the
BLANK
input is disabled, the ADV7177/ADV7178 automatically blanks all normally blank lines as per CCIR-624. Mode 3 is illustrated in
Figure 25 (NTSC) and Figure 26 (PAL).
