Re: [Amforth-devel] Atmega1280

[<an...@ki...>]

Looking at the quote below.

Are we actually saying here that the top 64k is not accessible then on a 
128k device ??

That the memory is arranged in Amforth in words (ie 16 bit) ??

Or that it is paged and therefore takes a bit more time to access ??

Sorry for being a bit dim.....

Cheers
