... extended addressing enhancements (which of course is a major departure from the classic 8051, Where does it say that? Asix said:
100% software compatible with standard 8051/80390 I didn't see any mention of "extended addressing enhancements" at http://www.asix.com.tw/products....4&PLine=72 - do I need to dig deeper? Those 'addressing enhancements' that I referred to are basically drawn from the fact they also promote the chip as a 'Dallas 80390 compatible', which has an extended program/data addressing scheme (i.e. implying up to 4MBytes separate program code/data or something like that - or even possibly more if they've got their own 'enhanced 80390' under the hood..) It is also worth mentioning that available stack space is increased somewhat by using the 80390 compatibility mode too. Cheers Valentin EDIT: Uncertain about inclusion of the math coprocessor (found in the 80390) on this variant, though judging by the '100% compatible' statement I would be inclined to say it's there. Full product details appear to be restricted from public view? |
