Clarify. The GPIOR0 is in a different address space from the other 2 GP 
registers. Why? Haven't a clue. They are not in the I/O space like ports. 
However, the manual leads you to believe that the SBI, CBI etc instructions 
work on all 3 registers. Not so.
The EIMSK is kind of sort of the same. Works with SBI and CBI but not the 
LDS or STS.
