    2929 === Outputs ===
    30 * Left/Right Hex Display Ports: The left and right hexadecimal displays contain seven individual on/off segments. These output ports drive 7-bit wide random numbers to the equivalent input ports on the User I/O core.
    31 * Red/Green LED Ports: The banks of red and green LEDs each contain 4 elements. These 4-bit wide random numbers drive the equivalent input ports on the User I/O core.
     30* Left/Right Hex Display Ports: These are unused in this WARP v2 variant of the Introduction to XPS exercise. They are tied to ground in XPS.
     31* Red/Green LED Ports: The banks of red and green LEDs each contain 4 elements. These 4-bit wide random numbers drive the external pins that are connected to LEDs on the board.
    3232* Captured Output Register: This register attaches to the bus and allows C-code executing inside the PowerPC to read the current latched output of the LFSR.
