Bit Description
SD_DUP_AV. This bit duplicates the AV codes
from the luma into the chroma path.
Reserved.
OF_SEL [3:0]. These bits allow 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. This bit allows VBI data (Lines 1 to 21)
to be passed through with minimum filtering.
RANGE. This bit allows the user to select the
range of output values. It can be ITU-R BT.656
compliant or fill the whole accessible number
range.
EN_SFL_PIN.
BL_C_VBI. Blank chroma during VBI. When
set, this bit enables data in the VBI region to
be passed through the decoder undistorted.
TIM_OE. Timing signals output enable.
Reserved.
Reserved.
BT.656. ITU-R BT.656-4 enable. This bit allows
the user to select an output mode compatible
with ITU-R BT.656-3 or ITU-R BT.656-4.
AD_PAL_EN. PAL B/G/I/H autodetect enable.
AD_NTSC_EN. NTSC autodetect enable.
AD_PALM_EN. PAL M autodetect enable.
AD_PALN_EN. PAL N autodetect enable.
AD_P60_EN. PAL 60 autodetect enable.
AD_N443_EN. NTSC 443 autodetect enable.
AD_SECAM_EN. SECAM autodetect enable.
AD_SEC525_EN. SECAM 525 autodetect enable.
CON [7:0]. Contrast adjust. This is the user
control for contrast adjustment.
Reserved.
