PRODUCTION DATA.
The DMA controller allows movement of data from one memory address to another without CPU intervention. 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. Table 6-9 lists the available triggers for DMA operation.
