The MCF5271 reference manual says that it has a 4GB address space but there are only 24 address pins. How do I interface 4GB of memory using 24 address pins. Also can someone explain the functionality of BS[3:0] pins in detail.
 
Also please send any document or notes which will help me understand.
 
Any help will be appreciated.
