/* The Nucleus2G has 3 LEDs... two on the Babel CAN board and a "heartbeat" LED."
* The LEDs on the Babel CAN board are capabl of OFF/GREEN/RED/AMBER status.
* In normal usage, the two LEDs on the Babel CAN board would show CAN status, but if
* CONFIG_ARCH_LEDS is defined, these LEDs will be controlled as follows for NuttX
* debug functionality (where NC means "No Change").
