    Okay. I am not sure which device you are using. But, FIFO mode in SPI can be enabled (or) disabled using SPIFFENA bit in SPIFFTX register. Writing a ‘1’ to this bit enables FIFO mode and writing ‘0’ disables FIFO mode.

    Manoj, I am using tms320f2812, and I know that i have to configure SPIFFENA to use FIFO interrupt, but I want to know how can i use the dsp without fifo interrupt, for example what is the function interrupt name? interrupt void spiRxFifoIsr this is the function name to use fifo interrupt. My question is the following: If I don't use fifo interrupt what is the function name that i can use with a normal spi interface? If you have an example I really apreciate your help. Thanks a lot.
