Mode 1—Slave Option (Subaddress 0x8A = X X X X X 0 1 0)
In this mode, the ADV7344 accepts horizontal sync and odd/even field signals. When HSYNC is low, a transition of the field input
indicates a new frame, that is, vertical retrace. The ADV7344 automatically blanks all normally blank lines as per CCIR-624. HSYNC and
FIELD are input on the S_HSYNC and S_VSYNC pins, respectively.
