Title:
AUDIO CONTROL CIRCUIT, HOST APPARATUS, AND RELATED CONTROL METHOD
Document Type and Number:
Japanese Patent JP2022158860
Kind Code:
A
Abstract:
To solve problems of necessity of a large storage space for storing parameters of various kinds and increase of costs for storage devices and of an area of a print circuit board.SOLUTION: The present invention is directed to an audio control circuit having an USB interface circuit, a specific interface circuit, and a processing circuit. When the audio control circuit is operated, the processing circuit receives a plurality of parameters from a host apparatus through a specific interface circuit, and executes enumeration by using the plurality of parameters during enumeration between the audio control circuit and the host apparatus.SELECTED DRAWING: Figure 1
