The CC13x1x3 and CC26x1x3 device platform includes a DMA controller, known as μDMA. The μDMA controller provides a way to offload data transfer tasks from the Arm® Cortex®-M4 processor, allowing more efficient use of the processor and the available bus bandwidth. The μDMA controller can perform transfers between memory and peripherals. Channels in the μDMA are dedicated for each supported on-chip module and can be programmed to automatically perform transfers between peripherals and memory, because the peripheral is ready to transfer more data.
