Programmable vendor identification circuitry and associated method

Abstract

An integrated circuit device and associated method are disclosed utilizing on-chip programmable circuitry that receives and stores vendor identification information, in particular, for devices meeting operational requirements of the Audio CODEC '97 Component Specification. The programmable circuitry allows for vendor ID information for multiple device configurations and/or multiple vendor supplied devices to be accurately reported to external devices. In particular, direct-access-arrangement (DAA) circuitry is disclosed having such on-chip programmable circuitry that may be loaded with vendor identification information at least in part from an external source. The external source may in turn be programmable circuitry, such as a EEPROM. This disclosed invention allows a single hardware DAA solution to be utilized by different software vendors, who each add their own respective software functionality, and to be utilized by a single software vendor, who desires to bundle different software functionality or revisions with the single hardware DAA solution. In this way, an integrated circuit may be designed and manufactured to provide a single hardware solution for a variety of different software or other programmable configurations.
