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 (default)

Bits [3:0]

0000 = WST SECAM

0001 = WST PAL B

0010 = WST PAL C

0011 = WST NTSC

0100 = NABTS NTSC

0101 = TTX NTSC-J

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.

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).
