DATA BYTE
DESCRIPTION
LINE
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); this bit mask is effective only, if the lines are enabled by
TTXOVS/TTXOVE and TTXEVS/TTXEVE

DESCRIPTION
VER
version identification of the device: it will be changed with all versions of the IC that
have different programming models; current version is 001 binary
closed caption bytes of the odd field have been encoded
the bit is reset after information has been written to the subaddresses
67H and 68H; it is set immediately after the data has been encoded
closed caption bytes of the even field have been encoded
the bit is reset after information has been written to the subaddresses
69H and 6AH; it is set immediately after the data has been encoded
state of the internal field sequence counter, with bit O_E as LSB
(repetition rate: NTSC = 4 fields, PAL = 8 fields)
