It checks MB flag if message was transmitted successfully or not, if yes updates driver variable and calls TXconfirmation.</P> <P>BR, Petr</P> Mon, 22 May 2023 11:59:42 GMT https://community.nxp.com/t5/S32K/What-s-different-between-Can-MainFunction-Write-and-quot-Can/m-p/1654804#M23149 PetrS 2023-05-22T11:59:42Z
