Table 3-26: Code conversion parameters (cont.)
Parameters Description
Past Output The portion in which you view the output data that was output first. You can
view up to eight points of the conversion result of the past output.
Output Code Writes the resulting data of conversion that is output when all the above four
conditions are satisfied. You may specify 16 points of data.
If all conditions from Past Source to Past Output are satisfied in the
conditions portion, Output Code will be output.
Past Source, Current Source, Next Source, and Past Output are defined as
conditions segments, and Output Code as the output segment.
Operations in the dialog box can be made as follows:
H A pattern must have been defined in at least one cell within a line conditions
segment on one line.
H The number of points in a cell may be optional, unless it exceeds the
maximum number of points. Any blank cell is ignored during pattern
matching.
H Each cell must be a pattern of 0s, 1s, and/or don’t care (minus) signs.
H The maximum definable number of lines is 256 lines.
The following information explains the code conversion mechanism:
H Initial state: The left end of source data is defined as the noticed point. Past
Source and Output Code data are regarded as all 0 data.
H The left and right patterns to the noticed point are compared with the
individual lines of the conditions segment in the conversion table. The
comparison is from the top to the bottom to find identical lines. If such lines
are found, the Output Code data defined in the line is added to the output
data.
H The noticed point shifts to the right. The amount of shift corresponds to the
size of the Current Source data that was found to identical in the source data.
The new noticed point is defined there.
H The above compare process for the individual lines is repeated for the new
noticed point.
H An error is caused if there are no identical lines found during the compare
process.
