9.7.6 Exclusive Or
The Exclusive Or function links the two Boolean inputs with the "xor"
operation and supplies the result to its Boolean output.
The output is "1" if precisely one of the two inputs is "1". If both of
the inputs are "0" or if both of the inputs are "1", then the output will
be "0". One can also say that the output is then precisely "1" if the
two inputs are not equal.
The following log table makes this function clear.
