LINE[20:13] Individual lines in both fields (PAL counting) can be disabled for insertion
Rev. 03 — 9 December 2004
Description
Individual lines in both fields (PAL counting) can be disabled for insertion
of teletext by the respective LINE bits. Disabled line = LINEnn (50 Hz
field rate). This bit mask is effective only, if the lines are enabled by
TTXOVS/TTXOVE and TTXEVS/TTXEVE.
Description
of teletext by the respective LINE bits. Disabled line = LINEnn (50 Hz
field rate). This bit mask is effective only, if the lines are enabled by
TTXOVS/TTXOVE and TTXEVS/TTXEVE.
Description
0 = enables NABTS (FISE = 1) or European teletext (FISE = 0); default
state after reset,
1 = enables World Standard Teletext 60 Hz (FISE = 1).
MSB of the last active line code; see
0 = new teletext protocol selected: at each rising edge of TTXRQ a
single teletext bit is requested; see
1 = old teletext protocol selected: the encoder provides a window of
TTXRQ going HIGH; the length of the window depends on the chosen
teletext standard; see
MSB of the first active line code; see
MSB of the 9-bit code that selects the last line of occurrence of signal
on pin TTXRQ in even field; see
MSB of the 9-bit code that selects the last line of occurrence of signal
on pin TTXRQ in odd field; see
MSB of the 9-bit code that selects the first line of occurrence of signal
on pin TTXRQ in even field; see
MSB of the 9-bit code that selects the first line of occurrence of signal
on pin TTXRQ in odd field; see
