Oh, I just missed the io mapped in your previous email. Unfortunately, my experience is only limited to memory map. I think they should be the same.

You are absolutly right and i guess it will certainly work for 8248 as well ,
but the only concern is that " here in mine case the register is not memory
mapped where as its IO mapped " we have to consider the memory as IO port
and then access the data ....

What you have used i guess its memory mapped ...Is it that accessing memory
mapped is same as io mapped ?????
