3.11.4 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. To the left of the vertical line, the user may pick different configurations for EP2&4 and EP6&8, since none

of the 512-byte buffers are combined between these endpoint groups. An example endpoint configuration would be:

EP2—1024 double buffered; EP6—512 quad buffered.

To the right of the vertical line, buffers are shared between EP2–8, and therefore only entire columns may be chosen.

3.11.5 Default Full-Speed Alternate Settings

Notes:

1. “0” means “not implemented.”

2. “2x” means “double buffered.”
