Function Explanation

NOT is used for the bitwise NOT operation taking the inverse of the value of a variable or constant
and the result is output to Out.
The operational rule:
If one bit of the input variable is TRUE, the corresponding bit of the output variable is FALSE. If one
bit of the input variable is FALSE, the corresponding bit of the output variable is TRUE.


The data type of Out must be the same as In.

Precautions for Correct Use
The input variables are not allowed to omit. An error will occur during the compiling of the software if any
input variable is omitted. But the output variable is allowed to omit.
