Detailed Description

DMAMSPM0 Hardware attributes.

This structure contains the error interrupt attributes.

dmaIsrFxn is the DMA peripheral's interrupt handler.

intPriority is priority of the DMA peripheral's error interrupt, as defined by the underlying OS. It is passed unmodified to the underlying OS's interrupt handler creation code, so you need to refer to the OS documentation(FreeRTOS) for usage. If the driver uses the ti.dpl interface instead of making OS calls directly, then the HwiP port handles the interrupt priority in an OS specific way.

A sample structure is shown below:

#include <ti/driverlib/dl_dma.h>

#include <ti/drivers/dma/DMAMSPM0.h>

DMAMSPM0_Object dmaMSPM0Object;

const DMAMSPM0_HWAttrs DMAMSPM0HWAttrs =
{
    .dmaIsrFxn = NULL,
    .intPriority = DEFAULT_DMA_PRIORITY,
    .roundRobinPriority = false,
};
