These set the endpoint EPx{x=a-e}.
These should be set to ensure that the EndpointNumber and INxOUT combination does not duplicate other
endpoints.
Bit7
INxOUT
This sets the endpoint transfer direction.
Bit6
IntEP_Mode
This sets the interrupt transfer.
Do not set this bit to "1" for bulk endpoints.
This bit setting will vary depending on the endpoint direction (IN or OUT) (the endpoint direction is
set by Bit7 "INxOUT").
The toggle sequence bit operating mode is set for the IN direction (INxOUT = 1). The toggle
sequence operating mode depends on the application. Select the operating mode for the Interrupt IN
endpoint.

For detailed information on this mode, refer to section 5.7.5 of the USB 2.0 standards.
Whether or not PING flow control is used for this endpoint is set for the OUT direction (INxOUT =
0). Set this bit to "1" for the Interrupt OUT endpoint.
