Field Documentation

csEnable

uint16 Spi_McspiExternalDeviceConfigType::csEnable

Chip select functionality on/off

csMode

Spi_CsModeType Spi_McspiExternalDeviceConfigType::csMode

Select single or continuous mode Note: Applicable only for McSPI;

csPolarity

Spi_LevelType Spi_McspiExternalDeviceConfigType::csPolarity

Chip select pin polarity high or low

csIdleTime

Spi_DataDelayType Spi_McspiExternalDeviceConfigType::csIdleTime

CS idle time (Timing between clock and chip select) if single mode is chosen. Values in case of McSPI McSPI 0x00 - 0.5 clock cycles 0x01 - 1.5 clock cycles 0x02 - 2.5 clock cycles 0x03 - 3.5 clock cycles

clkDivider

uint32 Spi_McspiExternalDeviceConfigType::clkDivider

Clock divider. This is used to derive the required baudrate from the McSPI functional clock. This value should be 1 less than the actual divider value. So a value of 0 means the divider is 1.

Maximum allowed value of divider is 4095(12 bit register field)

clkMode

Spi_ClkMode Spi_McspiExternalDeviceConfigType::clkMode

Mode 0 = {0=CPOL,0=CPHA}; Mode 1={0,1}; Mode 2={1,0} Mode 3={1,1}

txRxMode

Spi_TxRxMode Spi_McspiExternalDeviceConfigType::txRxMode

TX and RX mode

startBitEnable

uint16 Spi_McspiExternalDeviceConfigType::startBitEnable

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

startBitLevel

Spi_LevelType Spi_McspiExternalDeviceConfigType::startBitLevel

Start-bit polarity used when startBitEnable is TRUE.

receptionLineEnable

Spi_DataLineReceiveType Spi_McspiExternalDeviceConfigType::receptionLineEnable

Defines the data lines selected for reception.

transmissionLineEnable

Spi_DataLineTransmitType Spi_McspiExternalDeviceConfigType::transmissionLineEnable

Defines the data lines selected for transmission.
