101 * \brief associatedIface the control (resp. data) interface that is bounded to this data (resp. control) interface
102 * If a reference block is designed to be fully integrated in Blast, nearly every data interface is bounded
103 * to a control interface that signals if the value presented on the interface is valid or not. associatedIface
104 * references this control interface if this is a data interface, and a data interface is this is a control interface.
105 * Note that the association is done by the call of setAssociatedIface() that must be done only for a control interface.
106 * (NB: a test is done in the method to prevent the other case).
