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.
