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
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.
