8-bit output rounding mode
00 = standard rounding (roundup/down)
01 = rounding controlled by pseudo random number generator
10 = error diffusion
11 = error diffusion gated with pseudo random number
generator
Only applicable to -24 part.
Clamp luma and chroma data in VIP modes (i.e., when
OUT_MODE[1]=1) to 1-254.75. Affects all output bytes except
control codes, raw data, and ancillary data fields.
0 = Disable
1 = Enable
Enable substitution of blanking data during horizontal and
vertical blanking intervals during VIP modes (i.e., when
OUT_MODE[1]=1)
0 = Disable
1 = Enable
VIP optional active line enable. In VIP modes, the transition of
the V-bit from 1 to 0 is determined by either the VBLANK register
or V656BLANK register.
0 = VBLANK
1 = V656BLANK
Source of IDID0 byte in VIP ancillary data
0 = IDID0 register
1 = Line Count from VBI Slicer
Determines the format of the data count field in ancillary data in
8-bit mode (MODE10B=0)
0 = Data Count is number of blocks of 4 UDWs, with padding
1 = Data Count is number UDWs
Bit [0] = VRESET_N
Bit [1] = HRESET_N
Bit [2] = ACTIVE
Bit [3] = FIELD
Bit [4] = CBFLAG
Bit [5] = VACTIVE
Bit [6] = VALID
When bit is set, invert polarity of output
