Register Descriptions (continued)
Video Bandwidth Register
This register enables the selection of alternative filters for use in the luma and chroma channels. There are currently
four filter options defined for the chroma channel, 4 filter options in the S-Video luma channel and two filter options
in the composite luma channel. The Table 19 and Table 20 below show the various settings.
Bit 6 (CVBW) outputs the S-Video luma signal on both the S-Video luma output and the CVBS output. A "1" in this
location enables the output of a black and white image on composite, thereby eliminating the degrading effects of
the color signal (such as dot crawl or false colors), which is useful for viewing text with high accuracy.
Bit 7 (FLFF) controls the flicker filter used in the 7/10’s scaling modes. In these scaling modes, setting FLFF to 1
causes a five line flicker filter to be used. The default setting of 0 uses a four line flicker filter.
