ADV7310/ADV7311
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 ADV7310/ADV7311 accept or generate horizon-
tal sync and odd/even field signals. A transition of the field input
when HSYNC is high indicates a new frame, i.e., vertical retrace.
The BLANK signal is optional. When the BLANK input is dis-
abled, the ADV7310/ADV7311 automatically blank 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,
and VSYNC on S_VSYNC.
