Set-up Data Buffer
A separate 8-byte buffer at 0xE6B8-0xE6BF holds the Set-up
data from a CONTROL transfer.

Endpoint Configurations (High-speed Mode)
• 3× 64 bytes
• 8 × 512 bytes (Endpoints 2, 4, 6, 8)
3.12.2
• EP0
• Bidirectional endpoint zero, 64-byte buffer
• EP1IN, EP1OUT
• 64-byte buffers, bulk or interrupt
• EP2,4,6,8
• Eight 512-byte buffers, bulk, interrupt, or isochronous. EP4
and EP8 can be double buffered, while EP2 and 6 can be
either double, triple, or quad buffered. For high-speed end-
point configuration options, see
Organization
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 opera-
tions. An example endpoint configuration would be:
