• Operation is enabled when (s1) or (s2) have been specified by same device as (d) (perfect match). An error occurs if the
device range of (n) point(s) from (s1) or (s2) partially matches (overlaps) the device range of (n) point(s) from (d).
Ex.
If 4 points of the device from (s2) and (d) match
b31 ∙∙∙ b0
W1, W0
W3, W2
W5, W4
W7, W6
If 4 points of the device from (s2), (d) match partially
b31 ∙∙∙ b0
W1, W0
W3, W2
W5, W4
W7, W6
• If the value specified for (n) is 0, processing is not performed.
• If an underflow or overflow occurs for operation result, the result will be as follows. In this case, the carry flag (SM700) does
not turn ON.

Operation error
Error code Description
(SD0/SD8067)
2820H The range of (n) point(s) of data starting from the device specified by (s1), (s2), or (d) exceed the corresponding device range.
2821H The device range for (n) point(s) beginning from (s1) overlaps with that of (n) point(s) starting from (d).
(Does not apply when same device has been specified for (s1) and (d).)
The device range for (n) point(s) beginning from (s2) overlaps with that of (n) point(s) starting from (d).
(Does not apply when same device has been specified for (s2) and (d).)
