Initial Value R/W Description
— R/W 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
Restriction 2: Do not set the same endpoint
— R/W Configuration number to which endpoint belongs
(2-bit configuration, settable values: 0, 1)
— R/W
00: Control transfer
01: Other than Control transfer
— R/W Interface number to which endpoint belongs (2-bit
configuration, settable values: 0 to 2)
— R/W
00: Control transfer
00 to 10: Other than Control transfer

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)

numbers. (Ex: Int0 -- Alt0 -- EP1,
