Preliminary Technical Data
MODE 3—MASTER/SLAVE OPTION
(TIMING REGISTER 0 TR0 = X X X X X 1 1 0 OR
X X X X X 1 1 1)
In this mode, the ADV7322 accepts or generates horizontal sync
and odd/even field signals. When HSYNC is high, a transition
of the field input indicates a new frame, i.e., vertical retrace. The
BLANK signal is optional. When the BLANK input is disabled,
ADV7322 automatically blanks all normally blank lines as per
CCIR-624. HSYNC is output in master mode and input in slave
mode on S_VSYNC, BLANK on S_BLANK, andVSYNC on
S_VSYNC.
