When the device number of S is less than the device number of D, the data is transferred in the order from  to .
Example 1
When X0.0 is ON, the instruction transfers the data in D0–D3 to D20–D23.
D0 D20
D1 D21
D2 D22
D3
D23
Example 2
To prevent overlapping the source and the destination, the data is transferred in the following way.
