Mode 1—Master Option
(Timing Register 0 TR0 = X X X X X 0 1 1)
In this mode, the ADV7310/ADV7311 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 ADV7310/ADV7311 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 is output
on the S_HSYNC, BLANK on S_BLANK, and FIELD on
S_VSYNC.
