SPI ( FLEXIO SPI, LPSPI)COM between two S32K MICROCONTROLLERS

Hello everybody, 

I want to communicate between two MCUs(S32K) via SPI: 

Master use LPSPI and the slave use FLEXIO SPI. 

Is there any way to configure the FLEXIO SPI driver to trigger an interrupt once the master finish the communication to read data by slave? 

Do you have any other idea to exchange the data between the two MCUs other then interrupts ?

Hi, FlexIO SPI driver support DMA, so you can configure DMA to generate interrupt at the end of the major loop. This would assume messages with constant length.
