Setup Data Buffer
A separate 8-byte buffer at 0xE6B8-0xE6BF holds the setup data
from a CONTROL transfer.
Endpoint Configurations (High Speed Mode)
Endpoints 0 and 1 are the same for every configuration. Endpoint
0 is the only control endpoint, and endpoint 1 can be either bulk
or interrupt. The endpoint buffers can be configured in any 1 of
the 12 configurations shown in the vertical columns. When
operating in full speed bulk mode, only the first 64 bytes of each
buffer are used. For example, in high speed the max packet size
is 512 bytes, but in full speed it is 64 bytes. Even though a buffer
is configured to be a 512 byte buffer, in full speed only the first
64 bytes are used. The unused endpoint buffer space is not
available for other operations. The following is an example
endpoint configuration:
EP2–1024 double buffered; EP6–512 quad buffered (column 8
