Bit Description
Reserved.
SFL_INV. This bit controls the behavior of the
PAL switch bit.
Reserved.
GDECEL [15:8]. See the Comments column.
GDECEL [7:0]. See the Comments column.
GDECOL [15:8]. See the Comments column.
GDECOL [7:0]. See the Comments column.
GDECAD. This bit controls the manner in
which decoded Gemstar data is inserted into
the horizontal blanking period.
Reserved.
CTI_EN. CTI enable.
CTI_AB_EN. CTI alpha blend enable. This bit
enables the mixing of the transient improved
chroma with the original signal.
CTI_AB [1:0]. CTI alpha blend control. These
bits control the behavior of the alpha-blend
circuitry.
Reserved.
DNR_EN. This bit enables or bypasses the
DNR block.
Reserved.
CTI_C_TH [7:0]. CTI chroma threshold. These
bits specify how big the amplitude step must
be to be steepened by the CTI block.
DNR_TH [7:0]. DNR threshold. These bits
specify the maximum edge that is interpreted
as noise and is therefore blanked.
CIL [2:0]. Count-into-lock. These bits determine
the number of lines the system must remain
in lock before reporting a locked status.
COL [2:0]. Count-out-of-lock. These bits
determine the number of lines the system
must remain out-of-lock before reporting
an unlocked status
SRLS. Select raw lock signal. Selects the
source for determining the lock status.
FSCLE. F
SC
lock enable.
