16.1.4 USB Modes Including USB Audio Mode

CSR8635 QFN supports a variety of USB modes which enables the USB interface to extend the functionality of a

CSR8635 QFN based stereo device.

CSR8635 QFN supports:

■ USB charger enumeration

■ USB soundcard enumeration (USB audio mode)

■ USB mass storage enumeration

USB audio mode enables the device to enumerate as a soundcard while charging from a USB master device, e.g. a

PC. In this mode, the device enumerates as either a stereo music soundcard (for high quality music playback) or a

bidirectional voice quality soundcard. This enables the device for either listening to music streaming from the USB host

device or for voice applications, e.g. Skype.
