How to set CFM Security Register on MOD5213 ?

Has anyone enabled the CFM Security register?

I would like to enable Flash security on the MOD5213 to prevent access by a BDM,
but the ColdFire manual states that the bits are not writable, so I cannot just set the bits in my program.
Does this mean that I need to somehow initialize this word for the loader?
But I found that the bits are set in file userflashasm.s .
Can I just edit that file to set the CFMSEC register and rebuild the system files?
Or can I really just set the bits in CFMSEC in my C-program?

Thanks,
