Abstract

An interface monitoring apparatus for an interface port for connecting a peripheral device to an interface chip by at least one first data line includes a capacitive element arranged between the interface chip and the interface port and which capacitively couples the first data line to the interface chip, a first monitoring circuit coupled to the first data line at the interface port and which monitors at least one device-end termination of the first data line and provides a first control signal in the event of it being identified that a termination for the first data line is not present, and a first deactivation circuit that permanently stops data traffic via the first data line of the interface port until the interface monitoring apparatus is reset when the first control signal has been provided by the first monitoring circuit.
