| RX_START_INT_RAW | when a separator char has been send it will produce uhci_rx_start_int interrupt. |
| TX_START_INT_RAW | when DMA detects a separator char it will produce uhci_tx_start_int interrupt. |
| RX_HUNG_INT_RAW | when DMA takes a lot of time to receive a data it will produce uhci_rx_hung_int interrupt. |
| TX_HUNG_INT_RAW | when DMA takes a lot of time to read a data from RAM it will produce uhci_tx_hung_int interrupt. |
| IN_DONE_INT_RAW | when a in link descriptor has been completed it will produce uhci_in_done_int interrupt. |
| IN_SUC_EOF_INT_RAW | when a data packet has been received it will produce uhci_in_suc_eof_int interrupt. |
| IN_ERR_EOF_INT_RAW | when there are some errors about eof in in link descriptor it will produce uhci_in_err_eof_int interrupt. |
| OUT_DONE_INT_RAW | when a out link descriptor is completed it will produce uhci_out_done_int interrupt. |
| OUT_EOF_INT_RAW | when the current descriptor’s eof bit is 1 it will produce uhci_out_eof_int interrupt. |
| IN_DSCR_ERR_INT_RAW | when there are some errors about the out link descriptor it will produce uhci_in_dscr_err_int interrupt. |
| OUT_DSCR_ERR_INT_RAW | when there are some errors about the in link descriptor it will produce uhci_out_dscr_err_int interrupt. |
| IN_DSCR_EMPTY_INT_RAW | when there are not enough in links for DMA it will produce uhci_in_dscr_err_int interrupt. |
| OUTLINK_EOF_ERR_INT_RAW | when there are some errors about eof in outlink descriptor it will produce uhci_outlink_eof_err_int interrupt. |
| OUT_TOTAL_EOF_INT_RAW | When all data have been send it will produce uhci_out_total_eof_int interrupt. |
| SEND_S_Q_INT_RAW | When use single send registers to send a short packets it will produce this interrupt when dma has send the short packet. |
| SEND_A_Q_INT_RAW | When use always_send registers to send a series of short packets it will produce this interrupt when dma has send the short packet. |
| DMA_INFIFO_FULL_WM_INT_RAW |
