ADCBufLPF3 Hardware Attributes.

A sample structure is shown below:

    },
}

Field Documentation

§ dataDmaTableEntryPri

volatile uDMAControlTableEntry* ADCBufLPF3_HWAttrs::dataDmaTableEntryPri

uDMA primary control table entry for the data DMA channel

§ dataDmaTableEntryAlt

volatile uDMAControlTableEntry* ADCBufLPF3_HWAttrs::dataDmaTableEntryAlt

uDMA secondary control table entry for the data DMA channel

§ auxDmaTableEntryPri

volatile uDMAControlTableEntry* ADCBufLPF3_HWAttrs::auxDmaTableEntryPri

uDMA primary control table entry for auxiliary DMA channel used to re-enable DMA triggers for the data DMA channel.

§ adcChannelLut

ADCBufLPF3_AdcChannelLutEntry const* ADCBufLPF3_HWAttrs::adcChannelLut

Pointer to a table of ADCBufLPF3_AdcChannelLutEntry's. When starting a conversion using ADCBuf_convert(), ADCBuf_Conversion.adcChannel is used as an index into this table

§ resolutionBits

ADCLPF3_Resolution_Bits ADCBufLPF3_HWAttrs::resolutionBits

Resolution of ADC-conversion.

§ dataDmaChannelMask

uint32_t ADCBufLPF3_HWAttrs::dataDmaChannelMask

Mask for the data DMA channel (1 << channel number)

§ auxDmaChannelMask

uint32_t ADCBufLPF3_HWAttrs::auxDmaChannelMask

Mask for auxiliary DMA channel (1 << channel number)

§ dataDmaSubscriberId

uint32_t ADCBufLPF3_HWAttrs::dataDmaSubscriberId

MCU event fabric subscriber ID for the data DMA channel to be used, as defined in driverlib/evtsvt.h. Must support EVTSVT_DMA_TRIG_ADC0TRG.

§ auxDmaSubscriberId

uint32_t ADCBufLPF3_HWAttrs::auxDmaSubscriberId

MCU event fabric subscriber ID for the auxiliary DMA channel to be used, as defined in driverlib/evtsvt.h. Must support EVTSVT_PUB_ADC_COMB.

§ intPriority

uint8_t ADCBufLPF3_HWAttrs::intPriority

ADC peripheral's interrupt priority. This value is passed unmodified to HwiP_construct().

§ adcRefPosDIO

uint8_t ADCBufLPF3_HWAttrs::adcRefPosDIO

DIO that the ADC positive reference is routed to. If no channel in the ADCBufLPF3_HWAttrs.adcChannelLut is using the external ADC reference, then this should be set to GPIO_INVALID_INDEX.

§ adcRefNegDIO

uint8_t ADCBufLPF3_HWAttrs::adcRefNegDIO

DIO that the ADC negative reference is routed to. If no channel in the ADCBufLPF3_HWAttrs.adcChannelLut is using the external ADC reference, then this should be set to GPIO_INVALID_INDEX.
