7.6 USB
PSoC includes a dedicated Full-Speed (12 Mbps) USB 2.0
transceiver supporting all four USB transfer types: control,
interrupt, bulk, and isochronous. PSoC Creator provides full
configuration support. USB interfaces to hosts through two
dedicated USBIO pins, which are detailed in the
Routing”
