S32K3xx sBOOT SIRC

Hi team,

SAF 1.0.5 in sBOOT provides configuration for FIRC measurements using CMU_FM_1.
However, equivalent configuration for SIRC (via CMU_FM_2) is missing.
What is the reason for this omission?

Hi Daniel,

SIRC is critical clock source for some safety related mechanisms, but that was missing in safety manual and our reqs.
It was identified recently and added into latest K3 1.0.6 release which is about to be released by end of year.

Kind Regards,
Radoslav
