     Hello,My English is not good,please do not mind。my question :

     When I want to know how to use K64's SPI slave mode to receive data, because I need after receiving a byte of data, an interrupt is generated, and then sent to the master based on the results received, but I found that disabling the FIFO , still receives two bytes of data, I would like to ask why this is?

     I am using the dspi_interrupt_transfer ksdk routine, his change to disable FIFO, the host sends two bytes, but I think in the case of a byte is received, the received data is then sent a second host sent out a byte.

Or who his impressions from the program, the grateful.
