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).

Reserved.
If one of these modes
is selected, the
