7.7.5. DMA Device Drivers

The HAL models a DMA transaction as being controlled by two endpoint devices: a receive channel and a transmit channel.

For more information about a complete description of the HAL DMA device model, refer to Using DMA Devices in the Developing Programs Using the Hardware Abstraction Layer section.

The DMA device driver interface is defined in sys/alt_dma_dev.h.
