The TTX control register allows operating parameters of the VBI data processor to be controlled. The TTX
mode selection is independent of PAL/NTSC mode, which is selected by the TVP5022. This effectively
controls the default framing code and data rate. Closed caption data is affected by 525 lines versus 625 lines
(but not NABTS/WST). For NTSC and PAL M, the CCD data search is on Line 21; for PAL B,G,H,I,N it is
on Line 22. Custom framing code affects teletext data ONLY – closed caption data always uses the default
sync pattern.

0 = No teletext search on line XX
1 = Search line XX for teletext data
NOTE: Line numbers in parentheses refer to 625 Line systems
In both VBI only and full field modes, the vertical interval lines can be individually enabled or disabled. Only
lines that are enabled are searched for the selected type of teletext data. This allows some amount of filtering
on a physical location basis. If closed caption data is enabled, this overrides the enable/disable bit for line
21 (22). If full field mode is enabled, all lines after the vertical interval are searched for the selected type of
teletext data. The registers are initalized to 0x00 on reset.
