Abstract
An interface transceiver (16) circuit and method for communicating transceiver control and status information between a signal processor (20) and either an audio source (12) or an audio sink (24). During transmission of digital audio data from audio source (12) and signal processor (20), a comparator (49) compares a cyclic redundancy check (CRCC) byte of a block of channel status information to a theoretical CRCC byte generated by a CRC generator (48). By comparing actual and theoretical CRCC bytes, comparator (49) indicates in a single bit whether audio data was transmitted correctly. Remaining bits of the CRCC byte are then used to transfer status information corresponding to transceiver (16). Similarly, during transmission of digital data from signal processor (20) to audio sink (24), a parity bit of a subframe of the digital data is used to transfer programming information from signal processor (20) to audio sink (24).
