Field Documentation

◆ mode

MIBSPI_Mode MIBSPI_OpenParams::mode

Controller or Peripheral mode

◆ transferMode

MIBSPI_TransferMode MIBSPI_OpenParams::transferMode

Blocking or Callback mode

◆ iCountSupport

Bool MIBSPI_OpenParams::iCountSupport

Support for multi icount in one transfer to achieve high throughput, this is only supported in blocking mode

◆ transferCallbackFxn

MIBSPI_CallbackFxn MIBSPI_OpenParams::transferCallbackFxn

Callback function pointer

◆ dataSize

uint32_t MIBSPI_OpenParams::dataSize

SPI data frame size in bits

◆ frameFormat

MIBSPI_FrameFormat MIBSPI_OpenParams::frameFormat

SPI frame format

◆ controllerParams

MIBSPI_ControllerModeParams MIBSPI_OpenParams::controllerParams

Configuration dedicated to controller mode, refer to MIBSPI_ControllerModeParams

◆ peripheralParams

MIBSPI_PeripheralModeParams MIBSPI_OpenParams::peripheralParams

Configuration dedicated to peripheral mode, refer to MIBSPI_PeripheralModeParams

◆ u

union { ... } MIBSPI_OpenParams::u

union to hold either controller mode or peripheral mode params

◆ pinMode

MIBSPI_PinMode MIBSPI_OpenParams::pinMode

Pin operation Mode, refer to MIBSPI_PinMode

◆ shiftFormat

MIBSPI_DataShiftFmt MIBSPI_OpenParams::shiftFormat

SPI Data shift format, refer to MIBSPI_DataShiftFmt

◆ dmaEnable

uint8_t MIBSPI_OpenParams::dmaEnable

DMA mode enable. When Dma mode is disable, SPI driver is operated in polling mode, there is while(1) loop waiting for hardware to finish

◆ edmaInst

ECC mode enable

◆ csHold

uint8_t MIBSPI_OpenParams::csHold

CS Hold enable

◆ txDummyValue

uint16_t MIBSPI_OpenParams::txDummyValue

16 bit value transmitted when no TX data is provided for SPI_tranfer()

◆ transferTimeout

uint32_t MIBSPI_OpenParams::transferTimeout

Transfer timeout in system ticks (Not supported with all implementations

◆ compatibilityMode

Bool MIBSPI_OpenParams::compatibilityMode

Enable Compatibility mode operation of MIBSPI. MIBSPI RAM will be disabled

◆ edmaLinkParamId

uint16_t MIBSPI_OpenParams::edmaLinkParamId

EDMA link channel id Needs to be set only if compatibility mode is TRUE The MIBSPI requries an additional param to terminate Tx transfer. This should be from the pool of free param sets

Link param id.
