S32K1xx LPSPI 4-wire Swapping SIN/SOUT

I’m interested if the HW peripheral supports using 4 wire SPI with the SOUT as input and SIN as output.


This seems to be the case according the reference manual.




Can you confirm internally that the HW peripheral supports 4 wire SPI with SIN and SOUT “swapped”.


Of course the master and slaves on each side will have to be reconfigured and swapped as master/slave.  Im just wondering if this enables swapping of ins for outs so one can change which side is master and which side is slave in the future if needed.
