The Universal Serial Bus (USB) MCU device complies with the Universal Serial Bus (USB) 2.0
specification, but it does NOT feature high-speed USB (480 Mbit/s).
Each pipe/endpoint can be configured in one of several transfer types. It can be associated with
one or more banks of a dual-port RAM used to store the current data payload. If several banks
are used (“ping-pong” mode), then one DPRAM bank is read or written by the CPU or the DMA
while the other is read or written by the USB macro core. This feature is mandatory for isochro-
nous pipes/endpoints.

The theoretical maximal pipe/endpoint configuration (1600 bytes) exceeds the real DPRAM size
(960 bytes). The user needs to be aware of this when configuring pipes/endpoints. To fully use
the 960 bytes of DPRAM, the user could for example use the configuration described in
30-2.
