0 = Video standard unchanged
1 = Video standard changed
FIFO full: unmasked
0 = FIFO not full
1 = FIFO was full during write to FIFO
The FIFO full error flag is set when the current line of VBI data cannot enter the FIFO. For
example, if the FIFO has only 10 bytes left and teletext is the current VBI line, then the FIFO full
error flag is set, but no data is written because the entire teletext line does not fit. However, if the
next VBI line is closed caption requiring only 2 bytes of data plus the header, then this goes into
the FIFO even if the full error flag is set.
