Abstract
A programmable arbitrary sequence direct memory access (DMA) controller accesses sequentially addressed memory locations (source or destination) using address pointer registers. Each sequentially addressed memory location containing an indirect memory address is stored in an address latch and used to access the actual non-sequential memory location to be accessed by the DMA transfer.
