- * This interrupt is asserted when the Non-Periodic TxFIFO is
- * either half or completely empty, and there is space for at least

- * (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

- * @otgint: OTG Interrupt (OTGInt)
- * The core sets this bit to indicate an OTG protocol event. The

- * The application can flush the entire RxFIFO using this bit, but

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

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

- * * 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

- * * To clear this interrupt, status mask bits that control the

- * @csftrst: Core Soft Reset (CSftRst)
- * Resets the hclk and phy_clock domains as follows:
- * * Clears the interrupts and all the CSR registers except the

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

- * - 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

- * 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

- * 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.
