Processing interrupts are generated when:
Exception Interrupts are generated when:
• Ready to accept IN data(EPINTx, TXINI=1)
• Received OUT data(EPINTx, RXOUTI=1)
• Received SETUP(EPINTx, RXSTPI=1)
• Stalled packet(EPINTx, STALLEDI=1)
• CRC error on OUT in isochronous mode(EPINTx, STALLEDI=1)
• Overflow in isochronous mode(EPINTx, OVERFI=1)
• Underflow in isochronous mode(EPINTx, UNDERFI=1)
• NAK IN sent(EPINTx, NAKINI=1)
• NAK OUT sent(EPINTx, NAKOUTI=1)
