Bit 5 INEPNM: IN token received with EP mismatch
Indicates that the data in the top of the non-periodic TxFIFO belongs to an endpoint other
than the one for which the IN token was received. This interrupt is asserted on the endpoint
for which the IN token was received.
Bit 4 ITTXFE: IN token received when TxFIFO is empty
Applies to nonperiodic IN endpoints only.
Indicates that an IN token was received when the associated TxFIFO (periodic/nonperiodic)
was empty. This interrupt is asserted on the endpoint for which the IN token was received.
Bit 3 TOC: Timeout condition
Applies only to Control IN endpoints.
Indicates that the core has detected a timeout condition on the USB for the last IN token on
this endpoint.
Bit 2 AHBERR: AHB error
This is generated only in internal DMA mode when there is an AHB error during an AHB
read/write. The application can read the corresponding endpoint DMA address register to
get the error address.
Bit 1 EPDISD: Endpoint disabled interrupt
This bit indicates that the endpoint is disabled per the application’s request.
Bit 0 XFRC: Transfer completed interrupt
This field indicates that the programmed transfer is complete on the AHB as well as on the
USB, for this endpoint.
