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

Figure 12. SDP Y S-VHS Combined Responses
The filter plots in Figure 12 show the S-VHS 1 (narrowest) to
S-VHS 18 (widest) shaping filter settings. Figure 14 shows the
PAL notch filter responses. The NTSC compatible notches are
shown in Figure 15.
