The VDP status register indicates whether data is available in either the FIFO or data registers, and status information
about the FIFO. Reading data from the corresponding register does not clear the status flags automatically. These
flags are only reset by writing a 1 to the respective bit. However, bit 6 is updated automatically.
FIFO full error:
0 = No FIFO full error
1 = FIFO was full during write to FIFO
The FIFO full error flag is set when the current line of VBI data can not enter the FIFO. For example, if the FIFO has
only 10 bytes left and teletext is the current VBI line, the FIFO full error flag is set, but no data is written because the
entire teletext line will not fit. However, if the next VBI line is closed caption requiring only 2 bytes of data plus the
header, this goes into the FIFO. Even if the full error flag is set.
FIFO empty:
0 = FIFO is not empty
1 = FIFO is empty
TTX available:
0 = Teletext data is not available
1 = Teletext data is available
CC field 1 available:
0 = Closed caption data from field 1 is not available
1 = Closed caption data from field 1 is available
CC field 2 available:
0 = Closed caption data from field 2 is not available
1 = Closed caption data from field 2 is available
WSS available:
0 = WSS data is not available
1 = WSS data is available
VPS available:
0 = VPS data is not available
1 = VPS data is available
VITC available:
0 = VITC data is not available
1 = VITC data is available
