variables to .
When the input value of is 1, the value input to is output from .
When the input value of is , the value input to is output from .
(Example) Word (signed) type data
(2) If a value input to is outside the range of number of pins of variable 's', an undefined
value is output from .
(No operation error occurs. In case of MUX_E, FALSE is output from ENO.)
