Field Documentation

◆ channelBufType

uint8 Spi_ChannelConfigType::channelBufType

Buffer Type IB/EB

◆ dataWidth

uint8 Spi_ChannelConfigType::dataWidth

Width of clock frame in bits. In case of McSPI, valid values are from 1 to 32 bits.

◆ defaultTxData

uint32 Spi_ChannelConfigType::defaultTxData

Default transmit value when TX buffer is NULL

◆ maxBufLength

Spi_NumberOfDataType Spi_ChannelConfigType::maxBufLength

Max data length for external or internal buffer in SPI words. In case of internal buffers, this represents the number of words to copy from application buffer to internal buffer in case of Spi_WriteIB() API or from internal buffer to application buffer in case of Spi_ReadIB(). The value of this should be less than or equal to the SPI configuration SPI_IB_MAX_LENGTH as this macro is is used for buffer allocation.

◆ transferType

Spi_TransferType Spi_ChannelConfigType::transferType

Start with MSB or LSB. Only MSB is supported.
