CSFM[2:0]: C shaping filter mode
allows selection from a range of
low-pass chrominance filters; if
either auto mode is selected,
the decoder selects the optimum
C filter depending on the CVBS
video source quality (good vs.
bad); nonauto settings force a C
filter for all standards and quality
of CVBS video

WYSFM[4:0]; wideband Y shaping
filter mode allows the user to
select which Y shaping filter is
used for the Y component of
Y/C, YPrPb, B/W input signals; it
is also used when a good quality
input CVBS signal is detected;
for all other inputs, the Y shaping
filter chosen is controlled by
YSFM[4:0]
