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
BT656-compliant, or can fill the
whole accessible number range.
EN_SFL_PIN
BL_C_VBI. Blank Chroma during
VBI. If set, enables data in the VBI
region to be passed through the
decoder undistorted.
TIM_OE. Timing signals output
enable.
Reserved
Reserved
BT656-4. Allows the user to select
an output mode compatible with
ITU-R BT656-3/4.
