Bit Description
MUX_2[3:0]. Manual
muxing control for MUX2.
This setting controls
which input is routed to
the ADC for processing.
Reserved.
MAN_MUX_EN. Enable
manual setting of the
input signal muxing.
LB_TH [4:0]. Sets the
threshold value that
determines if a line is
black.
Reserved.
LB_EL[3:0]. Programs the
end line of the activity
window for LB detection
(end of field).
LB_SL[3:0]. Program the
start line of the activity
window for LB detection
(start of field).
ST NOISE[10:0]. Noise
measurement.
ST_NOISE[10:8].
ST_Noise_Valid.
ST_NOISE[7:0].
Reserved.
SD_OFF_CB [7:0]. Adjusts
the hue by selecting the
offset for the Cb channel.
SD_OFF_CR [7:0]. Adjusts
the hue by selecting the
offset for the Cr channel.
SD_SAT_CB [7:0]. Adjusts
the saturation by affecting
gain on the Cb channel.
SD_SAT_CR [7:0]. Adjusts
the saturation by affecting
gain on the Cr channel.
NVBEG[4:0]. Number of
lines after l
set V high.
NVBEGSIGN.
NVBEGDELE. Delay V bit
going high by one line
relative to NVBEG (even
field).
NVBEGDELO. Delay V bit
going high by one line
relative to NVBEG (odd
field).
