* (GAHBCFG.PTxFEmpLvl).
* @hchint: Host Channels Interrupt (HChInt)
* The core sets this bit to indicate that an interrupt is pending
* on one of the channels of the core (in Host mode). The
* application must read the Host All Channels Interrupt (HAINT)
* register to determine the exact number of the channel on which

* application must clear the appropriate status bit in the Host
* Port Control and Status register to clear this bit.
* @fetsusp: Data Fetch Suspended (FetSusp)
* This interrupt is valid only in DMA mode. This interrupt
* indicates that the core has stopped fetching data for IN
* endpoints due to the unavailability of TxFIFO space or Request
* Queue space. This interrupt is used by the application for an
* endpoint mismatch algorithm.
* @incomplp: Incomplete Periodic Transfer (incomplP)
* In Host mode, the core sets this interrupt bit when there are
* incomplete periodic transactions still pending which are
* scheduled for the current microframe.
* Incomplete Isochronous OUT Transfer (incompISOOUT)
* The Device mode, the core sets this interrupt to indicate that
* there is at least one isochronous OUT endpoint on which the
* transfer is not completed in the current microframe. This
* interrupt is asserted along with the End of Periodic Frame
* Interrupt (EOPF) bit in this register.
* @incompisoin: Incomplete Isochronous IN Transfer (incompISOIN)
* The core sets this interrupt to indicate that there is at least
* one isochronous IN endpoint on which the transfer is not
* completed in the current microframe. This interrupt is asserted
* along with the End of Periodic Frame Interrupt (EOPF) bit in
* this register.
* @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)
* The core sets this bit when it fails to write an isochronous OUT
* 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)
* The core sets this bit to indicate that a suspend was detected
* on the USB. The core enters the Suspended state when there
* is no activity on the phy_line_state_i signal for an extended
* period of time.
* @erlysusp: Early Suspend (ErlySusp)
* The core sets this bit to indicate that an Idle state has been
* detected on the USB for 3 ms.
* @i2cint: I2C Interrupt (I2CINT)
* This bit is always 0x0.
* @ulpickint: ULPI Carkit Interrupt (ULPICKINT)
* This bit is always 0x0.
* @goutnakeff: Global OUT NAK Effective (GOUTNakEff)
* Indicates that the Set Global OUT NAK bit in the Device Control
* register (DCTL.SGOUTNak), set by the application, has taken
* effect in the core. This bit can be cleared by writing the Clear
* Global OUT NAK bit in the Device Control register
* (DCTL.CGOUTNak).
* @ginnakeff: Global IN Non-Periodic NAK Effective (GINNakEff)
* 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
* 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).
* @rxflvl: RxFIFO Non-Empty (RxFLvl)
* Indicates that there is at least one packet pending to be read
* from the RxFIFO.
* @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
* mode
* The register access is completed on the AHB with an OKAY

* @rxfflsh: RxFIFO Flush (RxFFlsh)
* The application can flush the entire RxFIFO using this bit, but
* must first ensure that the core is not in the middle of a

* The application must only write to this bit after checking that
* the core is neither reading from the RxFIFO nor writing to the

* The application must wait until the bit is cleared before

* @hsftrst: HClk Soft Reset (HSftRst)
* The application uses this bit to flush the control logic in the

* * FIFOs are not flushed with this bit.
* * All state machines in the AHB clock domain are reset to the
* Idle state after terminating the transactions on the AHB,

* * CSR control bits used by the AHB clock domain state
* machines are cleared.
* * To clear this interrupt, status mask bits that control the
* interrupt status and are generated by the AHB clock domain
* state machine are cleared.
* * Because interrupt status bits are not cleared, the application
* can get the status of any core events that occurred after it set
* this bit.
* This is a self-clearing bit that the core clears after all
* necessary logic is reset in the core. This may take several
* clocks, depending on the core's current state.
* @csftrst: Core Soft Reset (CSftRst)
* Resets the hclk and phy_clock domains as follows:

* - PCGCCTL.RstPdwnModule
* - PCGCCTL.GateHclk
* - PCGCCTL.PwrClmp
* - PCGCCTL.StopPPhyLPwrClkSelclk

* - GUSBCFG.FSIntf
* - GUSBCFG.ULPI_UTMI_Sel
* - GUSBCFG.PHYIf
* - HCFG.FSLSPclkSel
* - DCFG.DevSpd
* * 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
* core. Once this bit is cleared software should wait at least 3
* PHY clocks before doing any access to the PHY domain
* (synchronization delay). Software should also should check that
* bit 31 of this register is 1 (AHB Master is IDLE) before
* starting any operation.
* Typically software reset is used during software development
* and also when you dynamically change the PHY selection bits
* in the USB configuration registers listed above. When you
* change the PHY, the corresponding clock for the PHY is
* selected and used in the PHY domain. Once a new clock is

* (downstream-facing port), dp_pulldown and
* dm_pulldown are enabled. This must not toggle
* during normal opeartion.
* @hst_mode: When '0' the USB is acting as HOST, when '1'
* USB is acting as device. This field needs to be
* set while the USB is in reset.
* @tuning: Transmitter Tuning for High-Speed Operation.
* Tunes the current supply and rise/fall output
* times for high-speed operation.
* [20:19] == 11: Current supply increased
* approximately 9%
* [20:19] == 10: Current supply increased
* approximately 4.5%
* [20:19] == 01: Design default.
* [20:19] == 00: Current supply decreased
* approximately 4.5%
* [22:21] == 11: Rise and fall times are increased.
* [22:21] == 10: Design default.
* [22:21] == 01: Rise and fall times are decreased.
* [22:21] == 00: Rise and fall times are decreased
* further as compared to the 01 setting.
* @tx_bs_enh: Transmit Bit Stuffing on [15:8].
* Enables or disables bit stuffing on data[15:8]
* when bit-stuffing is enabled.
* @tx_bs_en: Transmit Bit Stuffing on [7:0].
* Enables or disables bit stuffing on data[7:0]
* when bit-stuffing is enabled.
* @loop_enb: PHY Loopback Test Enable.
* '1': During data transmission the receive is
* enabled.
* '0': During data transmission the receive is
* disabled.
* Must be '0' for normal operation.
* @vtest_enb: Analog Test Pin Enable.
* '1' The PHY's analog_test pin is enabled for the
* input and output of applicable analog test signals.
* '0' THe analog_test pin is disabled.
* @bist_enb: Built-In Self Test Enable.
* Used to activate BIST in the PHY.
* @tdata_sel: Test Data Out Select.
* '1' test_data_out[3:0] (PHY) register contents
* are output. '0' internaly generated signals are
* output.
* @taddr_in: Mode Address for Test Interface.
* Specifies the register address for writing to or
* reading from the PHY test interface register.
* @tdata_in: Internal Testing Register Input Data and Select
* This is a test bus. Data is present on [3:0],
* and its corresponding select (enable) is present
* on bits [7:4].
* @ate_reset: Reset input from automatic test equipment.
* This is a test signal. When the USB Core is
* powered up (not in Susned Mode), an automatic
* tester can use this to disable phy_clock and
* free_clk, then re-eanable them with an aligned
* phase.
* '1': The phy_clk and free_clk outputs are
* disabled. "0": The phy_clock and free_clk outputs
* are available within a specific period after the
* de-assertion.
