Brief

Spi_ChannelType

channelId

Channel ID.

uint8

channelBufType

Buffer Type IB/EB.

uint8

dataWidth

Width of clock frame in bits. In case of SPI, valid values are from 1 to 16 bits.

uint16

defaultTxData

Default transmit value when TX buffer is NULL.

Spi_NumberOfDataType

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.

Spi_TransferType

transferType

Start with MSB or LSB. Only MSB is supported.
