DATA BYTE
DESCRIPTION
LINE
individual lines in both elds (PAL counting) can be disabled for insertion of teletext by the respective
bits, disabled line = LINExx (50 Hz eld rate)
this bit mask is effective only, if the lines are enabled by TTXOVS/TTXOVE and TTXEVS/TTXEVE

DESCRIPTION
VER
version identication of the device: it will be changed with all versions of the IC that have
different programming models; current version is 000 binary
CCRDO
1
closed caption bytes of the odd eld have been encoded
0
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
CCRDE
1
closed caption bytes of the even eld have been encoded
0
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
FSEQ
1
during rst eld of a sequence (repetition rate: NTSC = 4 elds, PAL = 8 elds)
0
not rst eld of a sequence
O_E
1
during even eld
0
during odd eld
