Data Avail
Teletext Avail
This bit indicates that at least one completeteletext transaction is in the FIFO. This bit is cleared
when the FIFO is emptied.
FIFO Full
This bit indicates that the maximum number of complete teletext transactions is in the FIFO.
Tx Count
This value represents the number of completeteletext transactions in the FIFO.
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.

Interrupt Threshold (R/W)
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.

Interrupt Line Number (R/W)
Data Required
Interrupt Line Number [4:0]
Interrupt Line Number This value determines which video line number will be used to generate the teletext data, CC
even field and CC odd field bits in the interrupt status register. 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 will disable
the three interrupt signals that use this condition. The default value is 24 (18h).
Data Required
If this bit is set HIGH, the teletext data bit
will only be set if there is data in the FIFO. This bit
does not affect the
CC even field and CC odd field bits
.
The default value for this bit is 1.
