DESCRIPTION
7 to 0
LAL[7:0]
These are the 8 LSBs of the 9-bit code that determines the last active line. The MSB is
held in subaddress 7CH; see Table 72. LAL[8:0] = 0 coincides with the first field
synchronization pulse.
last active line = (LAL[8:0] + 3) for M-systems
last active line = LAL[8:0] for other systems

TTX60
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 Table 71.
0 = new teletext protocol selected: at each rising edge of TTXRQ a single teletext bit is
requested (see Fig.23); default state after reset
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 Fig.23)
MSB of the first active line code; see Table 70.
MSB of the 9-bit code that selects the last line of occurrence of signal on pin TTXRQ in
even field; see Table 69.
MSB of the 9-bit code that selects the last line of occurrence of signal on pin TTXRQ in
odd field; see Table 67.
MSB of the 9-bit code that selects the first line of occurrence of signal on pin TTXRQ in
even field; see Table 68.
MSB of the 9-bit code that selects the first line of occurrence of signal on pin TTXRQ in
odd field; see Table 66.

DESCRIPTION
7 to 0
LINE[12:5]
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.
