The slice data registers 1 to 4 (SDATA1 to SDATA4) are registers in which the slice results are
stored. The data is stored in LSB-first fashion, in order from the LSB side near the start bit. Figure
28.7 shows how to store the slice data.

Figure 28.7 Relationship between Slice Data and Slice Data Register
There are four slice data registers, in which are stored slice results when data slicing is completed
for each line specified by the slice line setting registers. At this time data is stored in the
corresponding registers, rather than in the slicing order.

Figure 28.8 Relationship between Slice Line Setting Register and Slice Data Register
These are 16-bit read-only registers. SDATA read operations should be performed after an even
(odd) field slice completion interrupt. If an SDATA register is read during a data slice operation,
an indeterminate value may be read; the register should not be read during operation.
