Field Documentation

§ amtDataXferred

size_t SPICC26XXDMA_Object::amtDataXferred

Number of frames transferred

§ bitRate

unsigned int SPICC26XXDMA_Object::bitRate

SPI bit rate in Hz.

When the SPI is configured as SPI slave, the maximum bitrate is 4MHz.

When the SPI is configured as SPI master, the maximum bitrate is 12MHz.

§ csnPin

PIN_Id SPICC26XXDMA_Object::csnPin

SPI CSN pin

§ currentTransaction

SPI_Transaction* SPICC26XXDMA_Object::currentTransaction

Ptr to the current transaction

§ currentXferAmt

size_t SPICC26XXDMA_Object::currentXferAmt

Size of current DMA transfer

§ dataSize

unsigned int SPICC26XXDMA_Object::dataSize

SPI data frame size in bits

§ frameFormat

SPI_FrameFormat SPICC26XXDMA_Object::frameFormat

SPI frame format

§ frameSize

SPICC26XXDMA_FrameSize SPICC26XXDMA_Object::frameSize

Data frame size variable
