8.2.1.1 AHB and APB Interfaces

As shown in the preceding figure, the PDMA has two interfaces—AHB-lite and APB. The APB interface is a 32-bit APB slave used for configuring the PDMA. DMA operations do not occur on the APB bus interface of the PDMA. The PDMA performs single cycle accesses on the AHB interface only and Burst mode is not supported.
