Fig. 6.1: DMA architecture
The DMA includes a set of AHB Master interfaces and a set of AHB Slave interfaces. The AHB Master interface actively
accesses memory or peripherals through the system bus according to the current configuration requirements, as a
port for data movement. The AHB Slave interface is used to configure the DMA interface and only supports 32-bit
access.
