Hi@Ganesh808
If you are using S32 DS + RTD, our S32 DS example code provides a demo of implementing the SENT protocol using flexio.

If you are using MBDT, here's a similar answer I've seen:

If you are developing a project using MBDT and encounter any problems, please ask in the MBDT forum next time. This is a dedicated forum for answering MBDT questions.
