An apparatus for interfacing an integrated circuit with external circuitry includes a transistor having an emitter coupled to a node for receiving a control current from the integrated circuit. Also provided is a plurality of data registers for storing test data words read from the data registers, and multiplexer that switches through a test data word read from a data register with the high clock frequency of the output clock signal to a data bus in a way dependent on a register selection control datum of a multi-position register selection control data vector. Substantially simultaneously with application of the profile to the character strings, a plurality of remotely located profiles are accessed. The placement response includes data identifying a second media data associated with the first media data. Each volume image manager on a storage system may manage and produce a volume image for each volume of the dataset stored to the storage system. In one embodiment, the carrier includes a die attach region and an edge region.
