7.5 Data Conversion Instructions
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.
Ex.
To store data in lower 8 bits of D11 to D16 into D12 to D14
• 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.
Operation error
(1): Filled with 00H.
Device range where the data to be linked is stored

(s)+0 to (s)+(n)-1
Error code
(SD0/SD8067)
Description
2820H
The range of (n) points of devices from the device number specified in (s) onwards exceed the corresponding device range.
The range of no. of bytes specified in (n) from the device number specified in (d) onwards exceed the corresponding device range.
