buffer

uint8_t* dx::usb::isoc::pipeline< pipe_t >dx::usb::isoc::pipeline::[struct].sync buffer

< explicit feedback: an asynchronous sink states its rate on an isoc endpoint of its own, one request per bus frame of a round; the platform stands the slots

every slot's packets, one per micro frame

frame

union isoc::frame* dx::usb::isoc::pipeline< pipe_t >dx::usb::isoc::pipeline::[struct].sync frame

per slot: its request's frame descriptors

micro_frames

uint32_t dx::usb::isoc::pipeline< pipe_t >dx::usb::isoc::pipeline::[struct].sync micro_frames

requests per frame: the feedback endpoint's interval at high speed

packet

uint32_t dx::usb::isoc::pipeline< pipe_t >dx::usb::isoc::pipeline::[struct].sync packet

3 byte states 10.14 samples per frame, 4 byte 16.16

rate

uint64_t dx::usb::isoc::pipeline< pipe_t >dx::usb::isoc::pipeline::[struct].sync rate
