C
/* x = SERCOM instance number */
/* SPI slave mode */
SPI_SLAVE_ERROR SERCOMx_SPI_ErrorGet(void)
Summary
Returns the error status of SPI transfer
Description
This function returns the error status of the last SPI transfer. Applicaiton must check the status of a transfer in the application callback and take appropriate action in case there is an error during the data transfer. Calling this API clears the error status flags.
Precondition
The SERCOMx_SPI_Initialize() should have been called
Parameters
None.
Returns
SPI_SLAVE_ERROR - SPI Slave Errors
Example
void SPIEventHandler(uintptr_t context ) { if (SERCOM0_SPI_ErrorGet() == SPI_SLAVE_ERROR_NONE) { nBytesAvailable = SERCOM0_SPI_ReadCountGet(); nBytesRead = SERCOM0_SPI_Read(APP_RxData, nBytesAvailable); } else { // Handle error } } SERCOM0_SPI_CallbackRegister(SPIEventHandler, (uintptr_t) 0);
Remarks
None.
