2 Interfacing the Am29200 RISC Microcontroller to the MACE Am79C940 Controller registers and memory structures with a single com-mand. This can produce a highly efficient DMA engine under complete control of the software kernel, but can also be interrupted by a higher priority task. Hardware DMA The Am29200 provides two on-chip DMA channels. The
