SLES043A
These registers program the specific VBI standard at a specific line in the video field.
Bit 7:
0 = Disable filtering of null bytes in closed caption modes
1 = Enable filtering of null bytes in closed caption modes (default)
In teletext modes, bit 7 enables the data filter function for that particular line. If it is set to 0, then the data filter
passes all data on that line.
Bit 6:
0 = Send VBI data to registers only.
1 = Send VBI data to FIFO and the registers. Teletext data only goes to FIFO. (default)
Bit 5:
0 = Allow VBI data with errors in the FIFO
1 = Do not allow VBI data with errors in the FIFO (default)
Bit 4:
0 = Do not enable error detection and correction
1 = Enable error detection and correction (when bits [3:0] = 1 2, 3, and 4 only) (default)
Bits [3:0]:
0000 = Reserved
0001 = WST PAL B
0010 = WST PAL C
0011 = WST NTSC
0100 = NABTS NTSC
0101 = TTX NTSC
0110 = CC PAL
0111 = CC NTSC
1000 = WSS PAL
1001 = WSS NTSC
1010 = VITC PAL
1011 = VITC NTSC
1100 = VPS PAL
1101 = Custom 1
1110 = Custom 2
1111 = Active video (VDP off) (default)
A value of FFh in the line mode registers is required for any line to be sliced as part of the full field mode.

Full field mode
This register programs the specific VBI standard for full field mode. It can be any VBI standard. Individual line
settings take priority over the full field register. This allows each VBI line to be programmed independently but
have the remaining lines in full field mode. The full field mode register has the same definitions as the line mode
registers (default 7Fh).
