Hi Vusal,
Please read the 70.6.1.9 Configuration 1 (CFGR1) of S32K3XXRM Rev8.
25-24 PINCFG Pin Configuration
Specifies the pins used for input and output data during serial transfers. This field is ignored when performing parallel transfers.
00b - SIN is used for input data; SOUT is used for output data
01b - SIN is used for both input and output data; only half-duplex serial transfers are supported
10b - SOUT is used for both input and output data; only half-duplex serial transfers are supported
11b - SOUT is used for input data; SIN is used for output data
Since the LPSPI of S32K3 has this function, it is OK to label the MISO and MOSI pins in this way.
Best Regards,
Robin
