(Timing Register 0 TR0 = X X X X X 1 0 1)
In this mode, the ADV7304A/ADV7305A can generate hori-
zontal and vertical SYNC signals. A coincident low transition of
both
HSYNC
and
VSYNC
inputs indicates the start of an odd
field. A
VSYNC
low transition when
HSYNC
is high indicates
the start of an even field. The
BLANK
signal is optional. When
the
BLANK
input is disabled, the ADV7304A/ADV7305A
automatically blanks all normally blank lines as per CCIR-624.
HSYNC
is output on the
S_HSYNC
pin,
BLANK
on the
S_BLANK
pin, and FIELD on the
S_VSYNC
pin.
