Difficult to find.
Also, the MSCP documentation will, and will not, tell you what you
need. MSCP is a packet-based communication protocol. The MSCP specs. will
describe the packets. How exactly you send those packets, and what
additional information is wrapped around them is controller specific, and
is dealt with in the programming manuals for that controller. So, the MSCP
manuals don't describe any registers, or stuff like that.

MSCP is very abstract for a hardware oriented person. :-)
