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.
