first line of occurrence of signal TTXRQ on pin TTXRQ_XCLKO2
(CLK2EN = 0) in odd field
last line of occurrence of signal TTXRQ on pin TTXRQ_XCLKO2
(CLK2EN = 0) in odd field
first line of occurrence of signal TTXRQ on pin TTXRQ_XCLKO2
(CLK2EN = 0) in even field
last line of occurrence of signal TTXRQ on pin TTXRQ_XCLKO2
(CLK2EN = 0) in even field
first active line = FAL + 4 for M-systems and FAL + 1 for other systems, measured in lines
last active line = LAL + 3 for M-systems and LAL for other system, measured in lines
individual lines in both fields (PAL counting) can be disabled for insertion of teletext by the respective
bits, disabled line = LINExx (50 Hz field rate)

line = (TTXOVS + 4) for M-systems
line = (TTXOVS + 1) for other systems
line = (TTXOVE + 3) for M-systems
line = TTXOVE for other systems
line = (TTXEVS + 4) for M-systems
line = (TTXEVS + 1) for other systems
line = (TTXEVE + 3) for M-systems
line = TTXEVE for other systems
FAL = 0 coincides with the first field synchronization pulse
LAL = 0 coincides with the first field synchronization pulse
this bit mask is effective only if the lines are enabled by TTXOVS/TTXOVE and TTXEVS/TTXEVE
0
1
enables NABTS (FISE = 1) or European TTX (FISE = 0); default after reset
enables world standard teletext 60 Hz (FISE = 1)
