19.4.1.3. Application Interface Unit

The application interface unit (AIU) generates DMA requests based on programmable FIFO buffer thresholds. The AIU generates interrupts to the GIC for both host and device modes. A DMA scheduler is included in the AIU to arbitrate and control the data transfer between packets in system memory and their respective USB endpoints.
