Beschreibung
Zusammenfassung:	The invention relates to a dynamically addressable slave unit, comprising a bus interface, an enable circuit having a switch and two control ports which are connected via the enable circuit. The enable circuit only releases the slave unit for assigning an address by an address signal provided at the bus interface when a control signal is provided at one of the control ports and when the switch of the release signal is open. Otherwise, the enable circuit locks the slave unit for the assigning of an address. The switch locks depending on whether a switching signal is provided at the bust interface directed to the address assigned to the slave unit. The invention further relates to a master unit for use with one or more dynamically addressable slave units, to slave units according to the invention, and to a method for dynamically addressing slave units according to the invention.
