I'm looking for the datasheet for this processor...TI has no record of
the part number and I'm having a heck of a time finding info about it.
 Apparently, it is "TMS320C54x based", whatever that means.  The
particular chip in question is, according to published accounts, in a
BGA package with number of pins ~ 75 (I had to count on the schematic,
and may have miscounted).

For those curious, this is the brain in my new MP3 player (see
http://www.neurosaudio.com).  The entire product is open source,
although they recently had some flap over something in their firmware
that required that they temporarily "re-close" it.  I'm trying to
figure out the function of some of the pins on the processor so I can
make some sense of the FM transmitting component and hopefully improve
it somewhat (within legal limits, of course! ;-).
