More Information
Summary:A circuit and a method for controlling an audio adapter are provided. The audio adapter includes a button and a microphone, and the microphone is adapted for generating a recorded data. The control circuit includes a button detection circuit, a first-in, first-out (FIFO) data buffer, a USB endpoint buffer, a mute circuit and a USB endpoint control circuit. The button detection circuit is used for detecting whether the button is triggered. The FIFO data buffer is used for storing the recorded data. The USB endpoint buffer is used for storing the recorded data. The mute circuit is used for controlling whether the recorded data is transmitted to the USB endpoint buffer according to whether the button is triggered. The USB endpoint control circuit is used for controlling whether the audio adapter outputs the recorded data according to whether the button is triggered.
