FIFO read data
This address is provided to access VBI data in the FIFO through the host port. All forms of teletext data
come directly from the FIFO, while all other forms of VBI data can be programmed to come from the
registers or from the FIFO. Current status of the FIFO can be found at address C6h and the number of
bytes in the FIFO is located at address C7h. If the host port is to be used to read data from the FIFO, the
output formatter must be disabled at address CDh bit 0. The format used for the VBI FIFO is shown in
Internal Control Registers
