Figure 107. SD Timing Mode 1, Slave Option, PAL
Mode 1—Master Option (Subaddress 0x8A = X X X X X 0 1 1)
In this mode, the ADV739x can generate horizontal synchronization and odd/even field signals. When HSYNC is low, a transition of the
field input indicates a new frame, that is, vertical retrace. The ADV739x automatically blanks all normally blank lines as per CCIR-624.
Pixel data is latched on the rising clock edge following the timing signal transitions. HSYNC and FIELD are output on the HSYNC and
VSYNC pins, respectively.

Mode 2— Slave Option (Subaddress 0x8A = X X X X X 1 0 0)
In this mode, the ADV739x accepts horizontal and vertical synchronization signals. A coincident low transition of both HSYNC and
VSYNC inputs indicates the start of an odd field. A VSYNC low transition when HSYNC is high indicates the start of an even field. The
ADV739x automatically blanks all normally blank lines as per CCIR-624. HSYNC and VSYNC are input on the HSYNC and VSYNC
pins, respectively.
