YSFM[4:0]. Selects Y-shaping filter mode
when in CVBS only mode.
Allows the user to select a wide range of low-
pass and notch filters.
If either auto mode is selected, the decoder
selects the optimum Y filter depending on
the CVBS video source quality (good vs. bad).

Control (cont.)
If one of these modes is selected, the
decoder does not change filter modes.
Depending on video quality, a fixed
filter response (the one selected) is
used for good and bad quality video.
Automatically selects a C filter based
on video standard and quality.
Selects a C filter for all video standards
and for good and bad video.
CSFM[2:0].
C-shaping filter mode allows the 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).
Non-auto settings force a C filter for all
standards and quality of CVBS video.
