Active video/full field
At power up, the host interface is required to program the VDP-configuration RAM (VDP-CRAM) contents with
the lookup table. This is done through port address C3h. Each read or write from to this address auto
increments an internal counter to the next RAM location. To access the VDP-CRAM, the line mode registers
(D0h–FCh) must be programmed with FFh to avoid a conflict with the 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. Theoretically, each line can be any VBI
mode because the VDP processes VBI data in a line by line. When changing modes, the VDP must allow the
current transaction to complete through the delays of the VDP before switching the line mode register’s
contents. It must also complete the loading of the line mode registers before the next line starts processing.
The switch pixel number is set through registers CBh and CCh. Output data is available either through the
VBI-FIFO (B0h) or through dedicated registers at 90h–AFh, both of which are available from the host port.
2.6
VBI FIFO and Ancillary Data in Video Stream
Sliced VBI data can be output as ancillary data in the video stream in ITU-R BT.656 mode. VBI data is output
during the horizontal blanking period following the line from which the data was retrieved. The following table
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 NTSC NABST standard.
