| EA | endpoint/channel address |
| STATTX | Status bits, for transmission transfers |
| DTOGTX | Data toggle, for transmission transfers |
| VTTX | Valid USB transaction transmitted |
| EPKIND | endpoint/channel kind |
| UTYPE | USB type of transaction |
| SETUP | Setup transaction completed |
| STATRX | Status bits, for reception transfers |
| DTOGRX | Data Toggle, for reception transfers |
| VTRX | USB valid transaction received |
| DEVADDR | Host mode |
| NAK | Host mode |
| LS_EP | Low speed endpoint host with HUB only 0 (B_0x0): Full speed endpoint 1 (B_0x1): Low speed endpoint |
| ERR_TX | Received error for an OUT/SETUP transaction |
| ERR_RX | Received error for an IN transaction |
| THREE_ERR_TX | Three errors for an OUT or SETUP transaction 0 (B_0x0): Less than 3 errors received. 1 (B_0x1): More than 3 errors received, last error is timeout error. 2 (B_0x2): More than 3 errors received, last error is data error (CRC error). 3 (B_0x3): More than 3 errors received, last error is protocol error (invalid PID, false EOP, bitstuffing error, SYNC error). |
