TTXHD
If TTX_WINDOW = 0 these 3 bits are unused.
If TTX_WINDOW = 1 these 3 bits are the MSBs of the register 0×2A; they are used
to specify the length of the teletext insertion window
Selects between TTXRQ (= 0) pulsation or TTXRQ (= 1) Window mode
Teletext disable bits corresponding to the lines 13-20 respectively, (111=all three
lines are disabled),
(MSB is for line 21, LSB is for line 23)
