(4) The upper 8 bits of the byte storage device designated by
bits are used.
(5) Linking is correctly processed even when the device range (
to be linked is stored overlaps with the device range (
will be stored.
For example, the following will take place in a case where the lower 8 bits of D11 to D16 are
to be stored at D12 to D14:

Operation Error
(1) In any of the following cases, an operation error occurs, the error flag (SM0) turns ON, and
an error code is stored into SD0.
• The range of the number of bytes designated by n following the device number
designated by
• The range of the number of bytes designated by n following the device number
designated by
Program Example
(1) The following program dissociates the data at D10 to D12 in byte units and stores it at D20
to D25 when X0 is turned ON.
