19.6.1.1. USB Data FIFO Address Map

These regions, available in both Host and Device modes, are a push/pop FIFO space for a specific endpoint or a channel, in a given direction. If a host channel is of type IN, the FIFO can only be read on the channel. Similarly, if a host channel is of type OUT, the FIFO can only be written on the channel.
