eLBC P5040

I am working with the P5040 microProcessor and I have some questions. 


P5040 eLBC has a 32 bits bus mixed data/address [LAD00..LAD31] but it also have 5 bits only for address: [LA27..LA31].

Does it means that I have a 37 bits address bus or just that LAD27..LAD31 are data only?


Another question I would appreciate it if you could answer me is about which are the bits that I should use if my device  connected to the Local Bus has less address inputs. I have seeing some schematics where, if just 25 address bits are needed, [LA05..LA30] are used. That is something that I don't understand, shouldn't [LA00..LA24] have been used?


I hope you understand what I mean and someone could help me. Thank you in advance,
