6.11.9 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.
