The ODDOS[1:0] bits allow offset between the odd and even fields. Thus VBIL9 can be lines 17,18 or 19 for ODD
fields while VBIL9 is still line 281 for EVEN fields. This extra controls account for variations of VBI data locations
from ODD and EVEN fields.
When Intercast or Teletext data is selected, an 8-bit user programmable register (TTFRAM) is provided for the
framing byte. The frame alignment processor uses this information to properly locate the first data bit on each line
1.7.4. Raw CVBS Data Output Format
When raw ADC data is selected as output in place of the normal YUV or RGB data. The following rules apply:
• For 656 type 8 bit outputs, The ADC data outputs with successive data points in place of the Cb, Y, Cr, Y data
stream.
• For 16 bit or 24 bit outputs, The ADC data is output on the Y[7:0] and C[7:0] output pins. At any CK2 clock 2
bytes of ADC data are output. The Y[7:0] bus represents data N while C[7:0] is data N+1.
• ADC data is only output during the region that HAV is active.
• All ADC outputs are limited to the range 1-254, thus a 0 or 255 value will not be output.
For the line selected mode described above using VBCVBS and VBIL, data is from the luma ADC only. If C ADC
data or the entire video line is required, configure OFMT bits.
1.7.5. Sliced Data Output Formats
While sliced data is available for many of the output formats, the target application is 656 output format. The
description of data format is limited to this mode. The S5D0127X01 allows this data to be output during active
video.
