Custom Sync Pattern
Framing Code [7:0]
If the custom sync bit is set in the control register, the sync comparator uses the contents of the sync pattern register
as the bit pattern for the teletext framing code. Otherwise, the default sync patterns are used. Relative to the sync
pattern register, incoming bits are shifted in MSB first. To illustrate; the default WST framing code would be specified
as 0xE4 and the default NABTS framing code would be specified as 0xE7 (although the MSB versus. LSB is
ambiguous for the latter).
NOTE:
The custom sync option is only valid for NABTS or WST messages; closed caption
always uses the EIA standard start bit pattern.

Teletext FIFO (R)
Teletext Data FIFO [7:0]
The teletext FIFO can be accessed via the regular teletext FIFO register at address B0.
Reading this location returns 1 byte from the FIFO that store teletext transactions. If the FIFO is empty, a read will
return the same value as the previous read
.
It s the driver software’s or application software’s responsibility to assure
that the correct number of bytes per transaction are read out from the teletext FIFO.
The transaction length depends
on the whether the data is NABTS, WST-NTSC or WST-PAL.

Closed Caption Data [7:0]
The closed caption data contains two bytes per transaction. To retrieve both bytes this register must be read twice.
The first read returns the first byte of the message; the second read returns the second byte. Further reads return
the first byte until new data is received.
In order to distinguish between closed caption data received in the odd and even fields, software can test the field
sequence status bit (Address 82h, bit 4).
