You can think of System.Storage_Elements.To_Address as a simple type
conversion. That is, on a system with 32 bit addresses, To_Address
(register_Address) will return a value of type Address with the value 
16#FE10_2000#.

On another system that has only 16 bit addresses, you might get
Constraint_Error or something.

'register_Address' is _not_ a variable; it does not occupy space in
RAM. In Ada terminology, it is a "named number"; in plain English,
it's a "constant".

I'm not sure what you are asking.

What are you doing with the result of the To_Address call? Show the
rest of the code!
