    Hi,

    A DMA is used to transfer data from one location to another without the use of the CPU. For example, a DMA can copy data from a module RAM to the CPU RAM and then interrupt the CPU. This makes the CPU avoid having to read the data directly from the module RAM, and the CPU can do other tasks while the DMA is transferring the data.

    Hope this helps. Which specific part are you working with?
