| Bit Number | Name | Reset Value | Function |
|---|---|---|---|
| [7:6] | EPx_Speed | 0 | Operating speed of the target device: 00: Unused (If selected, the target is assumed to be using the same connection speed as the USB controller.) 01: High 10: Full 11: Low When the core is not configured with the multipoint option, these bits should not be accessed. |
| [5:4] | EPx_Protocol | 0 | The Cortex-M3 processor (or fabric master)
should set this to select the required protocol for the receive endpoint: 00: Control 01: ISO 10: Bulk 11: Interrupt |
| [3:0] | EPx_Target Endpoint Number | 0 | The Cortex-M3 processor (or fabric master) should set this value to the endpoint number contained in the receive endpoint descriptor returned to the USB controller during device enumeration. |
