WYSFM[4:0], Wideband Y Shaping Filter Mode,
Address 0x18[4:0]
The WYSFM[4:0] bits allow the user to manually select a shaping
filter for good quality video signals, for example, CVBS with
stable time base, luma component of YPrPb, and luma component
of Y/C. The WYSFM bits are active only if the WYSFMOVR bit
is set to 1. See the general discussion of the shaping filter settings in
the Y Shaping Filter section.
