Detailed Description

Type define for an Audio class-specific extended endpoint descriptor. This contains extra information on the usage of endpoints used to stream audio in and out of the USB Audio device, and follows an Audio class-specific extended endpoint descriptor. See the USB Audio specification for more details.

See also
USB_Audio_StdDescriptor_StreamEndpoint_Spc_t for the version of this type with standard element names.
Regardless of CPU architecture, these values should be stored as little endian.

Field Documentation

uint8_t USB_Audio_Descriptor_StreamEndpoint_Spc_t::Attributes

Audio class-specific endpoint attributes, such as AUDIO_EP_FULL_PACKETS_ONLY.

USB_Descriptor_Header_t USB_Audio_Descriptor_StreamEndpoint_Spc_t::Header

Regular descriptor header containing the descriptor's type and length.

uint16_t USB_Audio_Descriptor_StreamEndpoint_Spc_t::LockDelay

Time required to internally lock endpoint's internal clock recovery circuitry.

uint8_t USB_Audio_Descriptor_StreamEndpoint_Spc_t::LockDelayUnits

Units used for the LockDelay field, see Audio class specification.

uint8_t USB_Audio_Descriptor_StreamEndpoint_Spc_t::Subtype

Sub type value used to distinguish between audio class-specific descriptors, a value from the Audio_CSEndpoint_SubTypes_t enum.
