CCDAT1
This byte contains the first byte of the decoded close-caption data as defined in EIA-608. In
order for this register to receive the CC data, VBINSRT must be programmed to a “1”, and
VYFMT[1:0] must be programmed with the value 3. The same applies to CCDAT2. For normal
NTSC Closed Caption decoding, ODDEN should be set to a “1”, VBIL12 should be
programmed with the value 1.

VBIL0..VBLI15
These 16 2-bit numbers select how the chip should decode the VBI data for each VBI line. For
60 Hz video, VBIL1 through VBIL15 correspond to lines 10 through 24 in the ODD field, and
lines 273 through 286 in the EVEN filed for NTSC (refer to NTSC line numbering convention).
For 50 Hz video, VBIL1 corresponds to line 7 in the ODD field, and line 320 in the EVEN field.
VBIL0 is used for all other lines not covered by VBIL1 through VBIL15.
0
Decode normal video.*
1
Decode Closed Caption data.
2
Decode Teletext data.
3
Decode WSS data.
