Thx for all of your replies that gave me clarifications.

Got some good info from the net regarding this - i have placed it

Generally, Processor families have two distinct address spaces
through which they can communicate with these memories and peripherals.

I would take exception with the use of "generally".
I/O-mapping seems to have been initiated by Intel
way back when and only the look-alikes (Zilog, et

True, the texas 9900 series and transputers had their I/O on serial
links, not mapped anywhere.
