3.1 DMA Controller
Instead of using interrupt handlers to read and process the result registers, it is possible to use the AVR XMEGA DMA Controller to move data from one or more result registers to memory buffers or other peripheral modules. This moving of data is done without CPU intervention, and leaves the CPU ready for other tasks, even without having to execute interrupt handlers.
For more information, refer to the device data sheet or the “AVR1304: Using the XMEGA DMA Controller” application note.
