Perhaps for a high level language compiler or interpreter used in projects =

where you don't need the full horse power of a streamlined asm program but =

instead quick development times. Something like a BASIC stamp but with rtos =

capabilities which is directed towards industrial automation applications =

instead of hobby applications.

Actually, the new features looks pretty much like improvements to better fi=
t =

high level languages and compilers.

This only makes sense if the new enhanced PIC 16 is much cheaper than its b=
ig =

brothers though and where you buy them by the thousands.
