Mode 2: Master Option
HSYNC, VSYNC, BLANK
(Timing Register 0 TR0 = X X X X X 1 0 1)
In this mode, the ADV7304A/ADV7305A can generate hori-
zontal and vertical SYNC signals. A coincident low transition of
both HSYNC and VSYNC inputs indicates the start of an odd
REV. A

field. A VSYNC low transition when HSYNC is high indicates
the start of an even field. The BLANK signal is optional. When
the BLANK input is disabled, the ADV7304A/ADV7305A
automatically blanks all normally blank lines as per CCIR-624.
HSYNC is output on the S_HSYNC pin, BLANK on the
S_BLANK pin, and FIELD on the S_VSYNC pin.
