FIFO read data [7:0]

FIFO read data [7:0]: This register is provided to access VBI FIFO data through the I2C interface. All forms of teletext data come directly from the FIFO, while all other forms of VBI data can be programmed to come from registers or from the FIFO. If the host port is to be used to read data from the FIFO, then bit 0 (host access enable) in the VDP FIFO output control register at subaddress C0h must be set to 1 (see Section 2.11.71).
