DESCRIPTION
CCEN
TTXEN
enables individual line 21 encoding; see Table 36
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

DATA BYTE
DESCRIPTION
RCV2S
start of output signal on RCV2 pin
values above 1715 (FISE = 1) or [1727 (FISE = 0)] are not allowed; first active pixel at analog
outputs (corresponding input pixel coinciding with RCV2) at RCV2S = 11AH [0FDH]
end of output signal on RCV2 pin
values above 1715 (FISE = 1) or [1727 (FISE = 0)] are not allowed; last active pixel at analog
outputs (corresponding input pixel coinciding with RCV2) at RCV2E = 694H (687H)

REMARKS
TTXHS
start of signal on pin TTXRQ; see Fig.14
PAL: TTXHS = 42H
NTSC: TTXHS = 54H
DATA BYTE
DESCRIPTION
REMARKS
TTXHL
length of TTXRQ window; only active at old TTX protocol:
bit TTXO = 1
indicates the delay in clock cycles between rising edge of TTXRQ
output and valid data at pin TTX
TTXHL = 0: TTXRQ = 1398LLC;
TTXHL = 15: TTXRQ = 1413LLC
minimum value: TTXHD = 2
