I'm going to study assembler.
I thought that's what " having same 8051 core" is all about. so, do
they all have different assembler instructions? and even if I create
small app which uses only 1 I/O port and timer - I'll not be able to
move it to another mcu without a lot of changes?
If you stick to the architectural features that are part of the common
set then yes, your code should be portable. Recommend that you download
a few of the device manuals from the major vendors to see what is the
same and what is different among them.
