The description of the "Active Region" is inconsistent between the documentation and the code. Who is correct?

Hi

It appears that Dcm_ActiveAddressOTARegion() has reversed the mapping from DCMOTAR=0/1 to the low/high value.

We've discussed DCMSTAT[DCMOTAR] before: https://community.nxp.com/t5/S32K/s32k312/td-p/1697583

Best Regards,
