In Autosar Description, it means 'data of element'. it means u8 or u16 or u32? How is it define in nxp s32k mcal?</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="IMG_0148.jpeg" style="width: 1037px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/271763i1CE9929B48A0D0CE/image-size/medium?v=v2&amp;px=400" role="button" title="IMG_0148.jpeg" alt="IMG_0148.jpeg" /></span></P><P> </P> Wed, 03 Apr 2024 07:31:57 GMT Higgs_Boson 2024-04-03T07:31:57Z https://community.nxp.com/t5/S32K/s32k-mcal-Spi/m-p/1839986#M33761 <P>Hi，</P><P>The autosar api Spi_SetupEB() in s32k mcal we have use in project, we wonder the passing parameter &nbsp;'Length' Meaning.
