ABSTRACT:
A selection system for configuring a device controller. The selection system includes a plurality of state machines each of which has a portion of the configuration information needed to inform a host, connected to the device controller via a serial bus, of the device configuration as well as the configuration, interface and endpoint information. The selection system also includes a selection circuit that selects one of the plurality of state machines in response to a selection code that can be set by a user manually or automatically by programming are register. The manual setting of the selection code is by means of a set of configurable pins which are selected as the default source of the selection code by the selection system.If there are available a variety of device configurations and associated interface and endpoint configurations, the selection system selects one of the device configurations and the associated other configuration information in response to the same selection code, thereby maintaining consistency between the device configuration information and the other associated configuration information.
