+ * This interrupt is asserted when the Non-Periodic TxFIFO is

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

+ * In Device mode, in the core sets this bit to indicate that an SOF

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

+ * * A Device mode register, when the core is operating in Host
