Bit Description
GDECOL[15:8]; see the
Comments column
GDECOL[7:0]
GDECAD; controls the
manner decoded Gemstar
data is inserted into the
horizontal blanking period
GDE_SEL_OLD_ADF
Reserved
CTI_EN; CTI enable
CTI_AB_EN; enables the
mixing of the transient
improved chroma with
the original signal
CTI_AB[1:0]; controls the
behavior of the alpha-
blend circuitry
Reserved
DNR_EN; enable or bypass
the DNR block
Reserved
CTI_C_TH[7:0]; specifies
how big the amplitude
step must be to be steep-
ened by the CTI block
DNR_TH[7:0]; specifies
the maximum edge that is
interpreted as noise and is
therefore blanked
CIL[2:0]; count into lock
determines the number of
lines the system must
remain in lock before
showing a locked status
COL[2:0]; count out of
lock determines the
number of lines the
system must remain out-
of-lock before showing a
lost-locked status
SRLS; select raw lock signal;
selects the determination
of the lock status
FSCLE; f
VS/FIELD; VSYNC or FIELD
output; 40-lead and
32-lead LFCSP only
