MCSPI_ChConfig Struct Reference

Detailed Description

MCSPI configuration parameters for the channel.

MCSPI channel parameters used with the MCSPI_chConfig() call. Default values for these parameters are set using MCSPI_ChConfig_init().

If NULL is passed for the parameters, MCSPI_chConfig() uses default parameters.

Field Documentation

◆ chNum

uint32_t MCSPI_ChConfig::chNum

Channel number. Refer MCSPI_ChannelId

◆ frameFormat

uint32_t MCSPI_ChConfig::frameFormat

MCSPI frame format. Refer MCSPI_FrameFormat

◆ bitRate

uint32_t MCSPI_ChConfig::bitRate

MCSPI bit rate in Hz

◆ csPolarity

uint32_t MCSPI_ChConfig::csPolarity

Polarity of the chip select signal. Refer MCSPI_CsPolarity

◆ trMode

uint32_t MCSPI_ChConfig::trMode

Channel transmit/receive mode. Refer MCSPI_TrMode

◆ inputSelect

uint32_t MCSPI_ChConfig::inputSelect

Input Select - D0 or D1. Refer MCSPI_InputSelect

◆ dpe0

uint32_t MCSPI_ChConfig::dpe0

Transmission enable/disable for D0. Refer MCSPI_TxEnable

◆ dpe1

uint32_t MCSPI_ChConfig::dpe1

Transmission enable/disable for D1. Refer MCSPI_TxEnable

◆ slvCsSelect

uint32_t MCSPI_ChConfig::slvCsSelect

MCSPI slave select signal detection. Applicable for Channel 0 and in slave mode only. Refer MCSPI_SlvCsSelect

◆ startBitEnable

uint32_t MCSPI_ChConfig::startBitEnable

Start bit D/CX added before SPI transfer. Polarity is defined by start bit level (below)

◆ startBitPolarity

uint32_t MCSPI_ChConfig::startBitPolarity

Start-bit polarity used when startBitEnable is TRUE Refer MCSPI_SbPolarity

◆ csIdleTime

uint32_t MCSPI_ChConfig::csIdleTime

Chip select time control. Refer MCSPI_CsIdleTime. This is applicable only in master mode

◆ defaultTxData

uint32_t MCSPI_ChConfig::defaultTxData

Default TX data to use when NULL pointer is provided for TX buffer. The actual data that is transmitted depends on the dataSize field
