Hi ahmad alharbi,

    kl46z256VLL4 uart don't have the ISO7816 function directly, so the reference manual didn't mention the details about ISO7816.

    Just a little description about it:

    So, if you want to use the ISO7816, you need to use the TPM and LPUART0 together.

    We have some application note about it, you can refer to it:

     1.AN5218: using LPUART realize the ISO7816 function

https://cache.nxp.com/docs/zh/application-note/AN5218.pdf?fromsite=zh 

   But, now, I just find the chinese version, didn't find the english version.  This is application take KL03 as an example, your KL46 can refer to it.

Maybe you can associate with some translation tool to read it, or you can refer to the code part directly in the document.
