<Data format>
The LC7454 can extract the Index Plus + format data.
If the line contains the 1x format data, the first 15 bits of the 32 bit data buffer are filled with ‘0’ and 16th bit becomes ‘1’.
The extracted data is stored is stored form 16th to 31st bit.
32 bit data output buffer
Five 32 bit data buffer are provided to store maximum of 5 line data in a field. If the data with correct format exists in the
selected lines, the extracted data are stored into the buffers by the order of line number. If correct data is not found on the
selected line, the data buffer is filled with ‘0’. All five data buffers are cleared by the line 10 sensing signal in the next field.
Therefore, the data have to be read out between LN26 and the line 10 of the next field.
Please read only the selected buffers. For example, if three lines are selected, read the first three 32 bit buffers only.
