Hello,

Im was wondering if it matters if i
change the order of the address pins
with the address lines of the micro.
(Same question for IO lines)

Something like this
MCU RAM
==========
ad 0 - a 7
ad 1 - a 6
ad 2 - a 5
ad 3 - a 0
ad 4 - a 1
ad 5 - a 2
ad 6 - a 3
ad 7 - a 4
etc...

This wont do any harm right?
