ADV7302A/ADV7303A
Mode 1: Slave Option
HSYNC, BLANK, FIELD
(Timing Register 0 TR0 = X X X X X 0 1 0)
In this mode the ADV7302A/ADV7303A accepts 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 ADV7302A/ADV7303A automatically blanks all
normally blank lines as per CCIR-624. HSYNC is input on the
S_HSYNC Pin, BLANK on the S_BLANK Pin, and FIELD on
the S_VSYNC Pin.
