Detailed Description

SPICC3200DMA Hardware attributes.

These fields are used by driverlib APIs and therefore must be populated by driverlib macro definitions. For CCWare these definitions are found in:

• driverlib/prcm.h
• driverlib/spi.h
• driverlib/udma.h
• inc/hw_memmap.h
• inc/hw_ints.h

A sample structure is shown below:

#if defined(__TI_COMPILER_VERSION__)
#pragma DATA_ALIGN(scratchBuf, 32)
#elif defined(__IAR_SYSTEMS_ICC__)
#pragma data_alignment=32
#elif defined(__GNUC__)
__attribute__ ((aligned (32)))
#endif
uint32_t scratchBuf;

const SPICC3200DMA_HWAttrs SPICC3200DMAHWAttrs[] = {
    {
        .baseAddr = GSPI_BASE,
        .intNum = INT_GSPI,
        .intPriority = (~0),
        .spiPRCM = PRCM_GSPI,
        .csControl = SPI_HW_CTRL_CS,
        .csPolarity = SPI_CS_ACTIVELOW,
        .pinMode = SPI_4PIN_MODE,
        .turboMode = SPI_TURBO_OFF,
        .scratchBufPtr = &scratchBuf,
        .defaultTxBufValue = 0,
        .rxChannelIndex = UDMA_CH6_GSPI_RX,
        .txChannelIndex = UDMA_CH7_GSPI_TX,
    },
    ...
};
