Mode 1—Master Option
(Timing Register 0 TR0 = X X X X X 0 1 1)
In this mode, the ADV7314 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
ADV7314 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
,
BLANK
on
S_BLANK
, and FIELD on
S_VSYNC
.
