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, 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 = WST SECAM
0001 = WST PAL B
0010 = WST PAL C
0011 = WST NTSC
0100 = NABTS NTSC C
0101 = NABTS NTSC D
0110 = CC PAL
0111 = CC NTSC
1000 = WSS/CGMS-A PAL
1001 = WSS/CGMS-A NTSC
1010 = VITC PAL
1011 = VITC NTSC
1100 = VPS PAL
1101 = Gemstar 2x 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.
