The only user [if any] of -12v would be the
daughtercard. It should have a specification for the
-12v, although I am confident that it doesn't exceed

It is economical, widely available, and proven.

dedicated to the debug JTAG port - you cannot use it
as a general purpose USB port.

TI's web site shows a third party [educational DSP]
that has an economical HPI card. [I keep telling
myself that I am going to evaluate it someday...]
