In the AN5413 cookbook the flags&nbsp;are written to 1 to clear them (e.g. in the function LPSPI1_receive_16bits). Is this necessary? Why do the flags&nbsp;need to be written when they are read-only? Is the Application Note correct or is the Reference Manual correct?</P></BODY></HTML> Fri, 27 Oct 2017 16:46:25 GMT https://community.nxp.com/t5/S32K/Receiving-in-LPSPI-Cookbook-AN5413-vs-Reference-Manual/m-p/729809#M1816 kt1003 2017-10-27T16:46:25Z Re: Receiving in LPSPI: Cookbook AN5413 vs Reference Manual https://community.nxp.com/t5/S32K/Receiving-in-LPSPI-Cookbook-AN5413-vs-Reference-Manual/m-p/729810#M1817 <HTML><HEAD></HEAD><BODY><P>Hi,</P><P>The reference manual is correct.</P><P>Tha flags are set/cleared depending on the number of words stored in the FIFOs.</P><P></P><P>Regards,</P><P>Daniel</P></BODY></HTML> Mon, 30 Oct 2017 15:27:13 GMT https://community.nxp.com/t5/S32K/Receiving-in-LPSPI-Cookbook-AN5413-vs-Reference-Manual/m-p/729810#M1817 danielmartynek 2017-10-30T15:27:13Z
