downarrowArbitration: Why is HADDR sometimes shown as an input to the arbiter?

Applies to:AMBA AHB

The address bus, HADDR, is not required as an input to the arbiter but in some system designs it may be useful to use the address bus to determine a good point to change over between bus masters. For example, the arbiter could be designed to change bus ownership when a burst of transfers reaches a quad word boundary.
