These bits are read only unless bit 4 = “0”.
00 = (M) NTSC
01 = (B, D, G, H, I, N) PAL
10 = (M) PAL
11 = Combination (N) PAL; also called (N_C) PAL
0 = Manual selection of video timing standard
1 = Auto detect of video timing standard

Setup Select
Typically, this bit should be a “1” during (M) NTSC and (M, N) PAL operation. Otherwise, it should
be a “0”.
0 = Video source has a 0 IRE blanking pedestal
1 = Video source has a 7.5 IRE blanking pedestal

Adaptive Sync Slice This bit specifies whether to use fixed or adaptive sync slicing. Adaptive sync slicing
Enable
automatically determines the midpoint of the sync amplitude to determine timing.
0 = Fixed sync slicing
1 = Adaptive sync slicing
