WYSFM [4:0]. Wideband Y-shaping filter
mode. These bits allow the user to select
which Y-shaping filter is used for the Y
component of Y/C, YPbPr, 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].
