1. An integrated circuit, comprising:
a functional circuit;
a setting memory for storing a setting data item; and
an input circuit for receiving signals via an input terminal, the input circuit comprising a first receiving circuit having
a first hysteresis and a second receiving circuit having a second hysteresis; the input circuit selectively connecting either
the first or the second receiving circuit to the input terminal depending on a value of the setting data item in order to
receive the signals and to provide the functional circuit with the signals.
