The slice detection registers 1 to 4 (SDTCT1 to SDTCT4) store information on data slice results.
Data slice result information includes the clock run-in detection flag, start bit detection flag, data
end detection flag, and run-in pulse count for the clock run-in period.
This information is useful for optimal positioning of the data slicer slice level, start bit detection
timing, and sampling clock generation timing.
There are four slice detection registers; data slice information results are stored in them on
completion of data slicing for each line specified by the slice line setting registers 1 to 4. Data is
stored not in slicing order, but in the corresponding registers. For information on the slice line
sequence, refer to section 28.3.2, Slice Sequence.
