If you look at the vrc4372 data sheet at:

http://www.necel.com/home.nsf/Createpage?OpenAgent&Microprocessors&V()R()+Series(TM)+64-Bit+MIPS(R)+RISC&Companion+Chips&&&&&&&

Then look at section 6.5, page 24. And as you can see in platform.S, the 7
segment display is IOPROF_06 and IOPROF_07.

For more than this, you're on your own, sorry :-/. Unless someone else out
there has done this.
