here's a rather complete documentation:
main page:
http://homepage2.nifty.com/cstation/imode.html
mfi spec:
http://homepage2.nifty.com/cstation/mfi_1.html
there's also detailed information how to control the
FM synthesis of the YMU759 (MA-2) which is used in
NEC N21i. with these controls you can not just produce
a much greater frequency range but also many other
interesting effects.
as far as i know the Toshiba T21i contains the same
rohm wavetable soundchip BU8772KN as the panasonic
P503i for example.
the page is in japanese but when translated with a
web translator like babelfish
( http://world.altavista.com/ ) it is pretty
understandable.
