 Function Explanation

OR is used for performing a bitwise logical OR operation of two or more variables or constants and
the result is output to Out. That is Out= In1 OR In2 OR…OR InN.
The operational rule:
When corresponding bits of all input variables are all FALSE, the corresponding bit of the output
variable is FALSE. Otherwise, the corresponding bit of the output variable is TRUE.
