bank. If the IN Pipe is composed of multiple banks, clearing the FIFOCON bit will switch to the
next bank. The RXIN and FIFOCON bits are then updated by hardware in accordance with the
status of the new bank.
Figure 24-5. Example with IN data banks.
24.14.1
CRC error (isochronous only)
A CRC error can occur during IN stage if the USB controller detects a bad received packet. In
this situation, the STALLEDI/CRCERRI interrupt is triggered. This does not prevent the RXINI
interrupt from being triggered.
