Description
Sync Processing Input Select.
Selects the sync source for the sync processor.
0 = Sync processing uses raw Hsync/SOGIN.
1 = Sync processing uses regenerated Hsync from sync filter.
Must be set to 1 for proper operation.
Must be set to default for proper operation.
Must be set to default for proper operation.
Sets the window of time around the regenerated Hsync leading
edge (in 25 nS steps) that sync pulses are allowed to pass through.
Hsync0 Detection Bit.
0 = Hsync0 is not active.
1 = Hsync0 is active.
Hsync1 Detection Bit.
0 = Hsync 1 is not active.
1 = Hsync 1 is active.
Vsync 0 Detection Bit.
0 = Vsync0 is not active.
1 = Vsync0 is active.
Vsync1 Detection Bit.
0 = Vsync1 is not active.
1 = Vsync1 is active.
SOG0 Detection Bit.
0 = SOG0 is not active.
