TTXOVS[7:0]
These are the 8 LSBs of the 9-bit code that determines the
rst line of occurrence of signal on pin TTXRQ in odd eld;
the MSB is held in subaddress 7CH (see Table 72).
PAL: TTXOVS = 05H;
NTSC: TTXOVS = 06H
line = (TTXOVS[8:0] + 4) for M-systems
line = (TTXOVS[8:0] + 1) for other systems

TTXOVE[7:0]
These are the 8 LSBs of the 9-bit code that determines the
last line of occurrence of signal on pin TTXRQ in odd eld.
The MSB is held in subaddress 7CH, see Table 72.
PAL: TTXOVE = 16H;
NTSC: TTXOVE = 10H
last line = (TTXOVE[8:0] + 3) for M-systems

These are the 8 LSBs of the 9-bit code that determines the
rst line of occurrence of signal on pin TTXRQ in even eld.
The MSB is held in subaddress 7CH, see Table 72.
PAL: TTXEVS = 04H;

FAL[7:0]
These are the 8 LSBs of the 9-bit code that determines the rst active line. The MSB
is held in subaddress 7CH, see Table 72. FAL[8:0] = 0 coincides with the rst eld
synchronization pulse.
first active line = FAL[8:0] + 4 for M-systems
first active line = FAL[8:0] + 1 for other systems
