Ex.
For example, when (n) is 5, data starting from (s) to the lower 8 bits of (s)+2 is stored into (d) through (d)+4.
• Setting the number of bytes by (n) automatically determines the 16-bit binary data range specified by (s) and the device
range specified by (d) for storing the separated byte data.
• If (n) is 0, no processing is performed.
• In the upper byte of the devices specified by (d) to hold byte data, 00Hs are automatically stored.
Ex.
To store data in D12 to D14 into the lower 8 bits of D11 to D16
• Even if the device range of the data to be separated and the device range for storing the separated data overlap, the
processing is performed normally.
Operation error

(SD0/SD8067)
Description
2820
The range of no. of bytes specified in (n) from the device number specified in (s) onwards exceed the corresponding device range.
The range of (n) points of devices from the device number specified in (d) onwards exceed the corresponding device range.
