Just a correction - since we are on the PIC12F675 (or 629), any read or write of general purpose RAM in bank 1 accesses bank 0. So the following does not pose...

Hi Marco, There are not many basic differences between the standard PICs and some "A" PICs talking from the Jal point of view. IF there are big differences in...
