no FIFO overflow
FIFO overflow has occurred; this bit is reset after this subaddress has been read
no FIFO underflow
FIFO underflow has occurred; this bit is reset after this subaddress has been read
version identification of the device: it will be changed with all versions of the IC that have
different programming models; current version is 010 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
during first field of a sequence (repetition rate: NTSC = 4 fields, PAL = 8 fields)
not first field of a sequence
during even field
