The Linked DMA Controller consists of three main parts
• A DMA core that executes transfers and communicates status to the core
• A channel select block that routes peripheral DMA requests and acknowledge signals to the DMA
• A set of internal channel configuration registers for tracking the progress of each DMA channel
The DMA has access to all system memory through the AHB bus and the AHB->APB bridge. It can load channel descriptors from mem-
ory with no CPU intervention.
