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 device that
have different programming models. Current version is 000 binary.
Closed caption bytes of the odd field have been encoded.
The bit is reset after information has been written to the subaddresses 67 and 68. 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 69 and 6A. It is set
immediately after the data has been encoded.
During first field of a sequence (repetition rate: NTSC = 4 fields, PAL = 8 fields).
Not first field of a sequence.
During even field.
During odd field.
