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 a 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 ten 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 two 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.

Number of words
This register is programmed to trigger an interrupt when the number of words in the FIFO exceeds this
value (default 80h). This interrupt must be enabled at address C1h. One word equals two bytes.
