At powerup the host interface is required to program the VDP-configuration RAM (VDP-CRAM) contents with the
lookup table (see Section 2.20.58). This is done through port address C3h. Each read from or write to this address
will auto increment an internal counter to the next RAM location. To access the VDP-CRAM, the line mode registers
(D0hFCh) must be programmed with FFh to avoid a conflict with the internal microprocessor and the VDP in both
writing and reading. Full field mode must also be disabled.
Available VBI lines are from line 6 to line 27 of both field 1 and field 2. Each line can be any VBI mode.
Output data is available either through the VBI-FIFO (B0h) or through dedicated registers at 90hAFh, both of which
are available through the I2C port.

VBI FIFO and Ancillary Data in Video Stream
Sliced VBI data can be output as ancillary data in the video stream in the ITU-R BT.656 mode. VBI data is output during
the horizontal blanking period following the line from which the data was retrieved. Table 22 shows the header format
and sequence of the ancillary data inserted into the video stream. This format is also used to store any VBI data into
the FIFO. The size of FIFO is 512 bytes. Therefore, the FIFO can store up to 11 lines of teletext data with the NTSC
NABTS standard.
