SPI and I2C non blocking transfer on KL27z

Hi all,
I'm trying to execute and interrupt based I2C and SPI transfer on a kl27z MCU on a FRDM-KL27Z board. Examples from the SDK points to the use of SPI/I2C_MasterTransferNonBlocking with a callback function to indicate transfer is finished. However I couldn't quite understand how TransferNonBlockin works and when the interrupt is triggered. Can anyone enlighten me? Also, I would like to know the correct way of setting up FIFO in SPI1 as it is not stated anywhere in the examples.

 

I've posted the question on the Kinetis SDK section but has yet to receive a response.

Any help is appreciated.

Thanks
