I don't understand the problem.  All we need is some register or
memory location that is guaranteed to keep it's value during a hard
reset of the processor. This can be NVRAM, or On-Chip-Memory, or some
register.  I am pretty sure you know this CPU much better than me, and
I am optimistic that you can find such a register.

Best regards,
