	 * @oepint: OUT Endpoints Interrupt (OEPInt)
	 *	The core sets this bit to indicate that an interrupt is pending

	 *	endpoint on which the interrupt occurred, and then read the

	 *	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

	 *	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

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

	 *	Indicates that the Set Global OUT NAK bit in the Device Control

	 *	Global OUT NAK bit in the Device Control register

	 *	Indicates that the Set Global Non-Periodic IN NAK bit in the
	 *	Device Control register (DCTL.SGNPInNak), set by the
	 *	application, has taken effect in the core. That is, the core has
	 *	sampled the Global IN NAK bit set by the application. This bit
	 *	can be cleared by clearing the Clear Global Non-Periodic IN

	 *	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

	 *	Queue. The half or completely empty status is determined by

	 *	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

	 *	(micro)frame number of 0.
	 * @hsftrst: HClk Soft Reset (HSftRst)
	 *	The application uses this bit to flush the control logic in the

	 *	can get the status of any core events that occurred after it set

	 *	Resets the hclk and phy_clock domains as follows:
	 *	* Clears the interrupts and all the CSR registers except the

	 *	* All module state machines (except the AHB Slave Unit) are
	 *	reset to the IDLE state, and all the transmit FIFOs and the
	 *	receive FIFO are flushed.
	 *	* Any transactions on the AHB Master are terminated as soon
	 *	as possible, after gracefully completing the last data phase of
	 *	an AHB transfer. Any transactions on the USB are terminated
	 *	immediately.
	 *	The application can write to this bit any time it wants to reset
	 *	the core. This is a self-clearing bit and the core clears this
	 *	bit after all the necessary logic is reset in the core, which
	 *	may take several clocks, depending on the current state of the
