Ex.
For example, when (n) is 5, lower 8 bits of data from (s) through (s+4) is stored into (d) through (d)+2.

• Setting the number of bytes by (n) automatically determines the byte data range specified by (s) and the device range
specified by (d) for storing the linked data.
• If (n) is 0, no processing is performed.
• The higher-order 8 bits of the device specified by (s) for storing byte data are ignored, and only the lower-order 8 bits are
applicable.

• Even if the device range of the data to be linked and the device range for storing the linked data overlap, the processing is
performed normally.
