Figure 23-9. USB device controller endpoint interrupt system.
Processing interrupts are generated when:
Ready to accept IN data(EPINTx, TXINI=1)
Received OUT data(EPINTx, RXOUTI=1)
Received SETUP(EPINTx, RXSTPI=1)
Exception Interrupts are generated when:
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)
