Bit Description
SD_DUP_AV. Duplicates
the AV codes from the
luma into the chroma
path.
Reserved.
OF_SEL [3:0]. Allows the
user to choose from a set
of output formats.
TOD. Three-state output
drivers. This bit allows the
user to three-state the
output drivers: P[19:0], HS,
VS, FIELD, and SFL.
VBI_EN. Allows VBI data
(Lines 1 to 21) to be
passed through with only
a minimum amount of
filtering performed.
RANGE. Allows the user to
select the range of output
values. Can be ITU-R
BT.656 compliant, or can fill
the whole accessible
number range.
EN_SFL_PIN.
BL_C_VBI. Blank chroma
during VBI. If set, it
enables data in the VBI
region to be passed
through the decoder
undistorted.
TIM_OE. Timing signals
output enable.
Reserved.
Reserved.
BT.656-4. Allows the user
to select an output mode
compatible with
ITU-R BT.656-3/4.
