DMA Controllers
The P5040/P5020 DMA controllers have internal and external controls to initiate and monitor DMA
activity. The reference board does not incorporate any specific devices that make use of the external
pin-controlled DMA controllers.
The P5040/P5020 DMA ports are connected to test points on the reference board to allow external
hardware control, as needed.
