## Functions
uint32_t | SPI_Open (SPI_T *spi, uint32_t u32MasterSlave, uint32_t u32SPIMode, uint32_t u32DataWidth, uint32_t u32BusClock)
| This function make SPI module be ready to transfer. By default, the SPI transfer sequence is MSB first and the automatic slave select function is disabled. In Slave mode, the u32BusClock must be NULL and the SPI clock divider setting will be 0. More...
void | SPI_Close (SPI_T *spi)
| Reset SPI module and disable SPI peripheral clock. More...
void | SPI_ClearRxFIFO (SPI_T *spi)
| Clear Rx FIFO buffer. More...
void | SPI_ClearTxFIFO (SPI_T *spi)
| Clear Tx FIFO buffer. More...
void | SPI_DisableAutoSS (SPI_T *spi)
| Disable the automatic slave select function. More...
void | SPI_EnableAutoSS (SPI_T *spi, uint32_t u32SSPinMask, uint32_t u32ActiveLevel)
| Enable the automatic slave select function. Only available in Master mode. More...
uint32_t | SPI_SetBusClock (SPI_T *spi, uint32_t u32BusClock)
| Set the SPI bus clock. Only available in Master mode. More...
void | SPI_SetFIFOThreshold (SPI_T *spi, uint32_t u32TxThreshold, uint32_t u32RxThreshold)
| Set Tx FIFO threshold and Rx FIFO threshold configurations. More...
uint32_t | SPI_GetBusClock (SPI_T *spi)
| Get the actual frequency of SPI bus clock. Only available in Master mode. More...
void | SPI_EnableInt (SPI_T *spi, uint32_t u32Mask)
| Enable FIFO related interrupts specified by u32Mask parameter. More...
void | SPI_DisableInt (SPI_T *spi, uint32_t u32Mask)
| Disable FIFO related interrupts specified by u32Mask parameter. More...
