(Timing Register 0 TR0 = X X X X X 0 1 1)
In this mode, the ADV7304A/ADV7305A can generate hori-
zontal 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 ADV7304A/ADV7305A automatically
blanks all normally blank lines as per CCIR-624. Pixel data is
latched on the rising clock edge following the timing signal
transitions.
HSYNC
is output on the
S_HSYNC
pin,
BLANK
on the
S_BLANK
pin, and FIELD on the
S_VSYNC
pin.
