Description
Bit 8 of LAL
0 =New TTX protocol selected. At each rising edge of TTXRQ a
single TTX bit is requested.
1 = Old TTX protocol selected. The encoder provides a window of
TTXRQ. The length of the window depends on the chosen TTX
standard.

Individual lines in both fields (PAL counting) can be disabled for
insertion of teletext by the respective bits.
Disabled line =LINExx(50Hz field rate).
Bit 7 = Line 12; Bit 0 = Line 5
The mask is only effective if the lines are enabled via
TTXOVS/TTXOVE and TTXEVS/TTXEVE.

Line count array programming data lower 8 bits
Line count array programming data upper 6 bit
Line count array programming address
Writing to this address initiates the transfer of the data previously
written into locations 80 and 81 into an internal register array.
