I would assume that that is not available for anyone outside Intersil.
One might be able to get driver programmer's documentation after signing
NDA, but it does not cover MAC processor specific stuff.

Because documentation or development environment for Intersil MAC is not
available..

Intersil ;-). They don't even want to tell you what programming language
was used for firmware coding (see Intersil knowledge base).

That probably depends on where you happen to live and local
legislation, etc. Anyway, good luck trying to disassemble the code
without even knowing the instruction codes or word length, etc. used in
the MAC processor ;-).
