OK. Based on your explanations, the access to bit-band address and corresponding bit-band alias address are actually through the SAME bus, and to the same address (the actual bit-band address). Then I understand why the access size needs to fit the bus size. I missed this concept in the book and always had the impression that access to alias region is using a separate bus.
Thanks!
