Bit Description
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.
