MODE 1—MASTER OPTION
(TIMING REGISTER 0 TR0 = X X X X X 0 1 1)
In this mode, the ADV7320/ADV7321 can generate horizontal
sync and odd/even field signals. When HSYNC is low, a transition
of the field input indicates a new frame, that is, vertical retrace.
The BLANK signal is optional. When the BLANK input is disabled,
ADV7320/ADV7321 automatically blank all normally blank lines
as per CCIR-624. Pixel data is latched on the rising clock edge
following the timing signal transitions. HSYNC , BLANK , and
FIELD are output on S_HSYNC , S_BLANK , and S_VSYNC ,
respectively.
