If an internal bus error occurs during a DMA transfer, the fatal bus error (FBI) interrupt is set in the EMACDMARIS register and the Access Error status (AE) bit field in the EMACDMARIS register indicates the type of error that caused the bus error. The DMA controller can resume operation only after soft resetting the Ethernet MAC and the re-initializing the DMA.
