CCD avail
This status bit indicates that closed caption data has been received. The status bit is cleared when
both of the two bytes have been read.
Tx count
This value represents the number of complete teletext transactions in the FIFO.
FIFO full
This bit indicates that the maximum number of complete teletext transaction is in the FIFO.
Teletext avail
This bit indicates that at least one complete teletext transaction is in the FIFO. This bit is cleared
when the FIFO is emptied.

Threshold Value [3:0]
Threshold value This value determines how many teletext transactions must be received before the teletext
threshold bit is set in the interrupt status register. The default value is 5.

Data Required
Interrupt Line Number [4:0]
Data required
If this bit is set HIGH, the teletext data bit in the interrupt status register A is only set if there
is data in the FIFO. This bit does not affect the CC odd field and CC even field bits in the
interrupt status register A. The default value for this bit is 1.
Interrupt line number
This value determines which video line number is used to generate the teletext data, CC even
field, and CC odd field bits in the interrupt status register A at address C0. The register value
is examined at the start of the line. Since there is no line 0, a value of all zeros in this register
disables the three interrupt signals that use this condition. The default value is 24 (18h).
