Data FIFO (DFIFO) access register map
These registers, available in both host and device modes, are used to read or write the 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.
Device IN Endpoint 0/Host OUT Channel 0: DFIFO Write Access
Device OUT Endpoint 0/Host IN Channel 0: DFIFO Read Access
Device IN Endpoint 1/Host OUT Channel 1: DFIFO Write Access
Device OUT Endpoint 1/Host IN Channel 1: DFIFO Read Access
