Blue amplitude coefficient
Start of teletext request pulses or start of window
If TTX_WINDOW = 0 then this register is used as the Pipeline delay between
TTXRQ and TTXDAT signals 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 0×31. (register 0×31 bit 3)
Brightness adjustment ( range: -128 to +127)
