While I haven't used it myself, in Barnes' "Programming in Ada" he gives an
example:
S : Status;
for Status use at 8#100#;
More to the point an example in the reference manual gives:
Device_Register : Medium;
for Device_Register'Size use Medium'Size;
for Device_Register'Address use
System.Storage_Elements.To_Address(16#FFFF_0020#);
Which is more like your example.
I hope this helps,
