NOR
NOT OR logic operation: The output value is only
true if all input values are false. The output value is
false if any one of the input values or several input
values are true.
XOR
EXCLUSIVE OR logic operation: The output value is
only true if an odd number of inputs is true and all
other inputs are false
The XOR logic is easy to understand if there are only
two inputs. The output is true if the two inputs are not
simultaneously true or false.
XNOR
EXCLUSIVE NOT OR logic operation: The output
value is only true if an even number of inputs is true
and all other inputs are false
The XNOR logic is easy to understand if there are
only two inputs. The output is true if the two inputs
are simultaneously true or false.
Status indicators
The value present at the input or the value to be
output at the output is "true".
The value present at the input or the value to be
output at the output is "false".

the "Limits" chapter.
