■Operation processing
• Selects the value to be output among the values input to variables (s1) to (s28) according to the value input to n, and
outputs the operation result from (d) in the same data type as that of variables (s1) to (s28).
When the input value of n is 1, the value input to (s1) is output from (d).
When the input value of n is n, the value input to (sn) is output from (d).
Ex.
Word (signed) type data

• If a value input to n is outside the range of number of pins of variable 's', an undefined value is output from (d).
(No operation error occurs. In case of MUX_E, FALSE is output from ENO.)
• The value to be input to n is word (signed) type data within the range from 1 to 28. (within the range of the number of pins
of variable 's')
• The value to be input to variable 's' is bit, word (signed), double word (signed), word (unsigned)/16-bit string, double word
(unsigned)/32-bit string, single-precision real, double-precision real, string, time, structure, or array type data.
• Rounding error may occur when specifying single-precision real or double-precision real type data to (s1) through (s28) by
programming tool.
For precautions when setting an input value using a programming tool, refer to the following.

• The number of pins of (s) can be changed in the range from 2 to 28.
