Mnemonic
The Universal Serial Bus (USB) MCU device complies with the Universal Serial Bus (USB) 2.0
specification in all speeds.
Each pipe/endpoint can be configured in one of several USB transfer types. It can be associated
with one, two or three banks of a DPRAM used to store the current data payload. If two or three
banks are used, then one DPRAM bank is read or written by the CPU or the DMA, while the
other is read or written by the UOTGHS core. This feature is mandatory for isochronous
pipes/endpoints.
