hello Alexander,

Thnx for ur reply...

But i would be grateful if u could clarify some doubts
that i have regarding ur posting...

when might information in the cofig. space change?
during a wake-up?

what i meant is: do we have to use additional memory
for the purpose of using configuration registers ...
can we adjust with just the PC memory.

Thanks Again,
