Register Descriptions

Flicker Filter Register
Symbol: FFR
Address: 01H
Bits: 2
The flicker filter register provides for adjusting the operation of the scan rate conversion/flicker filter. As a function
of the CH7003 scaling/filtering architecture, the selection of scaling modes affects the available selections of flicker
filtering. When operating in non-scaling modes (i.e., modes with scaling of 1/1), the FF[1:0] selects from four
different amounts of flicker reduction. When operating in modes with scaling other than 1/1, FF[1] selects from two
different amounts of flicker reduction, where bit FF[0] is ignored in these scaling settings. The tables below show
the various flicker filter settings.
Table 18. Non-scaled Modes (1/1 ratio)
Table 19. Scaled Modes (non1/1scale ratio)
Video Bandwidth Register
Symbol: VBW
Address: 03H
Bits: 7
This register enables the selection of alternative filters for use in the luma and chroma channels. There are currently
4 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.
Table 20
and
Table 21
show the various settings.
