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, luma
component of YC. 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.
