Figure 105. SD Slave Mode 1, PAL
Mode 1—Master Option (Subaddress 0x8A = X X X X X 0 1 1)
In this mode, the ADV7340/ADV7341 can generate 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 ADV7340/ADV7341 automatically blank 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
S_HSYNC and S_VSYNC pins, respectively.

Figure 106. SD Timing Mode 1, Odd/Even Field Transitions (Master/Slave)
Mode 2— Slave Option (Subaddress 0x8A = X X X X X 1 0 0)
In this mode, the ADV7340/ADV7341 accept horizontal and vertical sync 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
ADV7340/ADV7341 automatically blank all normally blank lines as per CCIR-624. HSYNC and VSYNC are input on the S_HSYNC and
S_VSYNC pins, respectively.
