Identifies the possible events that can result from a transfer add request.

This enumeration identifies the possible events that can result from a transfer add request caused by the client calling either DRV_SPI_ReadTransferAdd or DRV_SPI_WriteTransferAdd or DRV_SPI_WriteReadTransferAdd functions.

Either DRV_SPI_TRANSFER_EVENT_COMPLETE or DRV_SPI_TRANSFER_EVENT_ERROR is passed in the "event" parameter of the event handling callback function that the client registered with the driver by calling the DRV_SPI_TransferEventHandlerSet function when a transfer request is completed.

When status polling is used, any one of these events is returned by DRV_SPI_TransferStatusGet function.
