3.12.3 Setup Data Buffer  
3.12 Endpoint RAM  
A separate 8 byte buffer at 0xE6B8-0xE6BF holds the setup data  
from a CONTROL transfer.  
3.12.1 Size  
3× 64 bytes  
(Endpoints 0 and 1)  
3.12.4 Endpoint Configurations (High Speed Mode)  
8 × 512 bytes (Endpoints 2, 4, 6, 8)  
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.  
3.12.2 Organization  
EP0  
The endpoint buffers can be configured in any 1 of the 12  
configurations shown in the vertical columns. When operating in  
the 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 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. An example endpoint configuration is the  
EP2–1024 double buffered; EP6–512 quad buffered (column 8).  
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; EP2 and 6 can be either double,  
triple, or quad buffered. For high speed endpoint configuration  
options, see Figure 5.
