Zusammenfassung:According to an aspect, there is provided a solution for providing an access to a slave unit. An address from a master unit trying to access a slave unit is received (400). The received address is mapped (402) to a slave address. Default access permissions are associated (404) to the master-slave connection. Additional access permissions associated with the master unit and the slave address are determined (406). The master-slave connection is enabled (408) if additional access permissions allow the master unit to access the slave, otherwise the connection is rejected.
