Endpoint number (4-bit configuration, settable
values: 0 to 8)
0000: Control transfer (EP0)
0001 to 1000: Other than Control transfer (EP1 to
EP8)
There are restrictions on settable endpoint
numbers according to the Interface number and
Alternate number to which the endpoint belongs.
Restriction 1: Set different endpoint numbers
under one Alternate.
However, there is no problem with
use of the same endpoint number if
the transfer directions (IN/OUT) are
different. (Ex: Alt0 -- EP1, EP2i,
EP2o)
Restriction 2: Do not set the same endpoint
number under different Interface
numbers. (Ex: Int0 -- Alt0 -- EP1,
EP2, Int1 -- Alt0 -- EP3)
