I use MCAL to configure the LPSPI of S32K146,I configured the LPSPI2 as slave mode

at the same time, I configured an external device in SpiExternalDevice Container

I choosed CSIB1 at SpiHwUnit,according to my understanding,the CISB1 is referred to SpiPhyUnit_1,but there is always an error which says their modes are different.

I wish to know how to avoid this problem
Thanks in advance.
