If TTX_WINDOW = 0 then this register is used as the Pipeline delay between
TTXRQ and TTXDAT signal in the teletext source. User programmable delay step
of 37 ns per LSB.
If TTX_WINDOW = 1 then this register is used as the 8 LSBs of the teletext insertion
windows; the 3 MSBs are located in register 0脳31. (register 0脳31 bit 3)
