DMA Controller (Link to user's guide)

The DMA controller allows movement of data from one memory address to another without CPU

intervention. For example, the DMA controller can be used to move data from the ADC10_A conversion

memory to RAM. Using the DMA controller can increase the throughput of peripheral modules. The DMA

controller reduces system power consumption by allowing the CPU to remain in sleep mode, without

having to awaken to move data to or from a peripheral.
