3) In the case of "1
≤
n
≤
3", the high-order {4
×
(4-n)} bits of
are set to "0".
For example, when "n" is "3", the low-order 4 bits of
to
+2 are stored in b0 to b11 of
,
and the high-order 4 bits of
are set to "0".

Errors
An operation error occurs in the following cases; The error flag M8067 turns ON, and the error code is stored
in D8067.
• When
to
+n are outside the specified device range (error code: K6706)
• When "n" is outside the range from "0 to 4" (error code: K6706)
Program example
In the program below, the low-order 4 bits of D0 to D2 are combined and stored in D10 when X000 turns ON.
