EasyDMA

nRF5340 Product Specification

AAR implements EasyDMA for reading and writing to RAM. EasyDMA will have finished accessing RAM when the END, RESOLVED, and NOTRESOLVED events are generated.

If the IRKPTR, ADDRPTR, and the SCRATCHPTR is not pointing to the Data RAM region, an EasyDMA transfer may result in a HardFault or RAM corruption. See Memory for more information about the different memory regions.
