Hello,

I am looking to implement monotonic/freshness counter in s32k1xx chip. I do not find the details of the monotonic counter in the reference manual.

Is there any separate documentation or could someone please brief me on this?

 

Thank you

Hello @subakshya,

Unfortunately, the CSEc engine on S32K1xx does not support monotonic counters.

It is supported by the HSE module on S32K3xx, for example.

 

Regards,

Daniel
