  Running lights
  Timer interrupt and LED example for the Kickstart card.
  Displays running lights on the Kickstart Card LED:s.

  Jumper settings:
  ----------------
  For ROM-monitor:
  Set JP4 (enables UART0, used for ROM-monitor communication).
  Set jumpers p0.2-p0.14, p0.16, p0.17 and p0.31 in the LED jumper block.

  For J-Link or Standalone:
  Set JP6 to JTAG1.
  Set jumpers p0.0-p0.15 in the LED jumper block.
