Should any combination other than the one shown above exist, DCD must take proper action. Transfer
failure mechanisms are indicated in the device error matrix.
In addition to checking the status bit, DCD must read the transfer bytes field to determine the actual bytes
transferred. When a transfer is complete, the total bytes transferred is decremented by the actual bytes
transferred. For transmit packets, a packet is only complete after the actual bytes reaches zero, but for
receive packets, the host may send fewer bytes in the transfer according to the USB variable length packet
protocol.
32.8.7.4
It is necessary for the DCD to flush to de-prime one more endpoints on a USB device reset or during a
broken control transfer. There may also be application specific requirements to stop transfers in progress.
The DCD can use the following procedure to stop a transfer in progress:
32.8.8
The following table summarizes packet errors that are not automatically managed by the USB controller.

The device controller manages all errors on bulk/control/interrupt endpoints except for a data buffer
overflow. However, for ISO endpoints, errors packets are not retried and errors are tagged as indicated.

This error also set the halt bit in the dQH and if there are dTDs remaining in the linked list for the endpoint, those are not
executed.

1. Write a 1 to the corresponding bit(s) in USB_ENDPTFLUSH.
2. Wait until all bits in USB_ENDPTFLUSH are 0.
3. Read USB_ENDPTSTATUS to ensure all endpoints commanded to be flushed are now 0. If the
Data Buffer Error = 0
corresponding bits are 1 after the second step has finished, flush has failed as described here:
In rare cases, a packet is in progress to the particular endpoint is commanded to flush using
USB_ENDPTFLUSH. A safeguard is in place to refuse the flush to ensure the packet in progress
completes successfully. The DCD may need to repeatedly flush any endpoints that fail to flush by
repeating steps one through three until each endpoint is successfully flushed.

Flushing/De-priming an Endpoint
This operation may take a large amount of time depending on the USB bus
activity. It is not desirable to have this wait loop within an interrupt service
routine.
