+ * Control and Status register to clear this bit.

+ * The Device mode, the core sets this interrupt to indicate that
+ * there is at least one isochronous OUT endpoint on which the

+ * Interrupt (EOPF) bit in this register.

+ * The core sets this interrupt to indicate that there is at least one
+ * isochronous IN endpoint on which the transfer is not completed

+ * @oepint: OUT Endpoints Interrupt (OEPInt)
+ * The core sets this bit to indicate that an interrupt is pending on
+ * one of the OUT endpoints of the core (in Device mode). The
+ * application must read the Device All Endpoints Interrupt
+ * (DAINT) register to determine the exact number of the OUT
+ * endpoint on which the interrupt occurred, and then read the
+ * corresponding Device OUT Endpoint-n Interrupt (DOEPINTn)
+ * register to determine the exact cause of the interrupt. The
+ * application must clear the appropriate status bit in the
+ * corresponding DOEPINTn register to clear this bit.
+ * @iepint: IN Endpoints Interrupt (IEPInt)
+ * The core sets this bit to indicate that an interrupt is pending on
+ * one of the IN endpoints of the core (in Device mode). The
+ * application must read the Device All Endpoints Interrupt
+ * (DAINT) register to determine the exact number of the IN
+ * endpoint on which the interrupt occurred, and then read the
+ * corresponding Device IN Endpoint-n Interrupt (DIEPINTn)
+ * register to determine the exact cause of the interrupt. The
+ * application must clear the appropriate status bit in the
+ * corresponding DIEPINTn register to clear this bit.
+ * @epmis: Endpoint Mismatch Interrupt (EPMis)
+ * Indicates that an IN token has been received for a non-periodic
+ * endpoint, but the data for another endpoint is present in the top
+ * of the Non-Periodic Transmit FIFO and the IN endpoint
+ * mismatch count programmed by the application has expired.
+ * @eopf: End of Periodic Frame Interrupt (EOPF)
+ * Indicates that the period specified in the Periodic Frame Interval
+ * field of the Device Configuration register (DCFG.PerFrInt) has
+ * been reached in the current microframe.
+ * @isooutdrop: Isochronous OUT Packet Dropped Interrupt (ISOOutDrop)

+ * packet into the RxFIFO because the RxFIFO doesn't have
+ * enough space to accommodate a maximum packet size packet
+ * for the isochronous OUT endpoint.
+ * @enumdone: Enumeration Done (EnumDone)
+ * The core sets this bit to indicate that speed enumeration is
+ * complete. The application must read the Device Status (DSTS)
+ * register to obtain the enumerated speed.
+ * @usbrst: USB Reset (USBRst)
+ * The core sets this bit to indicate that a reset is detected on the
+ * USB.
+ * @usbsusp: USB Suspend (USBSusp)

+ * This bit is always 0x0.
+ * @ulpickint: ULPI Carkit Interrupt (ULPICKINT)

+ * @goutnakeff: Global OUT NAK Effective (GOUTNakEff)
+ * Indicates that the Set Global OUT NAK bit in the Device Control

+ * Global OUT NAK bit in the Device Control register
+ * (DCTL.CGOUTNak).

+ * Indicates that the Set Global Non-Periodic IN NAK bit in the
+ * Device Control register (DCTL.SGNPInNak), set by the

+ * sampled the Global IN NAK bit set by the application. This bit
+ * can be cleared by clearing the Clear Global Non-Periodic IN
+ * NAK bit in the Device Control register (DCTL.CGNPInNak).
+ * This interrupt does not necessarily mean that a NAK handshake
+ * is sent out on the USB. The STALL bit takes precedence over
+ * the NAK bit.
+ * @nptxfemp: Non-Periodic TxFIFO Empty (NPTxFEmp)
+ * This interrupt is asserted when the Non-Periodic TxFIFO is
+ * either half or completely empty, and there is space for at least
+ * one entry to be written to the Non-Periodic Transmit Request
+ * Queue. The half or completely empty status is determined by
+ * the Non-Periodic TxFIFO Empty Level bit in the Core AHB
+ * Configuration register (GAHBCFG.NPTxFEmpLvl).

+ * Indicates that there is at least one packet pending to be read

+ * @sof: Start of (micro)Frame (Sof)
+ * In Host mode, the core sets this bit to indicate that an SOF
+ * (FS), micro-SOF (HS), or Keep-Alive (LS) is transmitted on the
+ * USB. The application must write a 1 to this bit to clear the
+ * interrupt.
+ * In Device mode, in the core sets this bit to indicate that an SOF
+ * token has been received on the USB. The application can read
+ * the Device Status register to get the current (micro)frame
+ * number. This interrupt is seen only when the core is operating
+ * at either HS or FS.
+ * @otgint: OTG Interrupt (OTGInt)
+ * The core sets this bit to indicate an OTG protocol event. The
+ * application must read the OTG Interrupt Status (GOTGINT)
+ * register to determine the exact event that caused this interrupt.
+ * The application must clear the appropriate status bit in the
+ * GOTGINT register to clear this bit.
+ * @modemis: Mode Mismatch Interrupt (ModeMis)
+ * The core sets this bit when the application is trying to access:
+ * * A Host mode register, when the core is operating in Device
+ * mode
+ * * A Device mode register, when the core is operating in Host

+ * The register access is completed on the AHB with an OKAY
