Mode 1—Master Option
(Timing Register 0 TR0 = X X X X X 0 1 1)
In this mode, the ADV7312 can generate 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
ADV7312 automatically blank all normally blank lines as per
CCIR-624. Pixel data is latched on the rising clock edge follow-
ing the timing signal transitions.
HSYNC
is output on the
S_HSYNC
,
BLANK
on
S_BLANK
, and FIELD on
S_VSYNC
.
