enables individual line 21 encoding; see Table 105
disables teletext insertion; default after reset
enables teletext insertion
selects the actual line, where Closed Caption or extended data are encoded;
line = (SCCLN + 4) for M-systems; line = (SCCLN + 1) for other systems
line 21 encoding off; default after reset
enables encoding in field 1 (odd)
enables encoding in field 2 (even)
enables encoding in both fields
active display window horizontal start; defines the start of the active TV display portion after
the border colour
active display window horizontal end; defines the end of the active TV display portion before
the border colour
start of signal TTXRQ on pin TTXRQ_XCLKO2
(CLK2EN = 0); see Fig.50
indicates the delay in clock cycles between rising edge
of TTXRQ output signal on pin TTXRQ_XCLKO2
(CLK2EN = 0) and valid data at pin TTX_SRES
advanced composite sync against RGB output from 0 XTAL clocks to 31 XTAL clocks
