Abstract
Caller ID (CID) data-reporting circuitry operates in conjunction with direct-access arrangement (DAA) circuitry or other circuitry that operates within the operational requirements of the Audio Codec '97 (AC-97) Component Specification. The CID data-reporting circuitry provides for the transfer of a data word from the DAA circuitry to a host computer or controller that operates within the AC-97 operational specifications. The CID data-reporting circuitry transfers the CID data in an asynchronous manner, i.e., at non-pre-determined intervals. Software running on the host computer or the controller may thus examine each data word or group of data words and take appropriate action, for example, process the data further or terminate the data transfer. A command interpreter begins the data transfer by initializing an address pointer used to facilitate retrieving the data from a CID random-access memory (RAM) and to make the data available to the host computer or controller through an output register.
