Detailed Description

A SPI_Transaction data structure is used with SPI_transfer(). It indicates how many SPI_FrameFormat frames are sent and received from the buffers pointed to txBuf and rxBuf. The arg variable is an user-definable argument which gets passed to the SPI_CallbackFxn when the SPI driver is in SPI_MODE_CALLBACK.
