Endpoint status
| ERBR0 | Endpoint receive buffer ready for physical OUT endpoints. This bit is set to 1 by hardware as a response to receiving a command from a corresponding bit in the ENDPTPRIME register. ERBR0 = endpoint 0 … ERBR3 = endpoint 3 |
| ERBR1 | Endpoint receive buffer ready for physical OUT endpoints. This bit is set to 1 by hardware as a response to receiving a command from a corresponding bit in the ENDPTPRIME register. ERBR0 = endpoint 0 … ERBR3 = endpoint 3 |
| ERBR2 | Endpoint receive buffer ready for physical OUT endpoints. This bit is set to 1 by hardware as a response to receiving a command from a corresponding bit in the ENDPTPRIME register. ERBR0 = endpoint 0 … ERBR3 = endpoint 3 |
| ERBR3 | Endpoint receive buffer ready for physical OUT endpoints. This bit is set to 1 by hardware as a response to receiving a command from a corresponding bit in the ENDPTPRIME register. ERBR0 = endpoint 0 … ERBR3 = endpoint 3 |
| RESERVED | Reserved |
