Hello,

Are the MISO and MOSI pins labeled incorrectly in the CANHUBK344 Eval Board Schematic?

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

Hi Robin,

Thank you for pointing this out! It makes sense in that case.

Best,
