S32K342_SPI_Data lines swap possible

[gunasekart]

Hi Team,

We are using the S32K342 (S32K342NHT0MPBSR) controller. We want to know the whether we can swap the data lines of SPI as we required. In our board we are using PTB2 as output and PTB3 as input. In this case it is not working. If we change the PTB2 as input and PTB3 as output we are able to get the response.

But as per MUX sheet, i think it can be able to achieve by swapping. Please confirm

Hi @gunasekart 

For full-duplex communication, SOUT goes to SOUT and SIN to SIN. Besides half-duplex communication, SOUT goes to SIN, in this mode SOUT and SIN can be configured as input/output.
