General Description The DMA Component transfers data to and from memory, Components, and registers. These transfers occur independent of the CPU. The DMA transfers can be set up in a byte, halfword (2 bytes), or word (4 bytes) wide. The DMA starts each transaction through an external trigger that can come from a DMA channel (including itself), another DMA channel, a peripheral, or the CPU. The DMA is best used to offload data transfer tasks from the CPU. |
