DMA Controller
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 wake to move data to or
from a peripheral.
