/* The CC3200 LaunchPad has three RGB LEDs.
 *
 *   BOARD_LED_R    -- Connected to PF1
 *   BOARD_LED_G    -- Connected to PF3
 *   BOARD_LED_Y    -- Connected to PF2
 *
 * If CONFIG_ARCH_LEDS is defined, then automated support for the LaunchPad LEDs
 * will be included in the build:
 *
 * OFF:
 * - OFF means that the OS is still initializing. Initialization is very fast so
 *   if you see this at all, it probably means that the system is hanging up
 *   somewhere in the initialization phases.
 *
 * GREEN
 * - This means that the OS completed initialization.
 *
 * YELLOW:
 * - Whenever and interrupt or signal handler is entered, the YELLOW LED is
 *   illuminated and extinguished when the interrupt or signal handler exits.
 *
 * RED:
 * - If a recovered assertion occurs, the RED component will be illuminated
 *   briefly while the assertion is handled.  You will probably never see this.
 *
 * Flashing RED:
 * - In the event of a fatal crash, the YELLOW and GREEN components will be
 *   extinguished and the RED component will FLASH at a 2Hz rate.
 *
 *                          RED  YELLOW BLUE
 * LED_STARTED       0      OFF  OFF   OFF
 * LED_HEAPALLOCATE  0      OFF  OFF   OFF
 * LED_IRQSENABLED   0      OFF  OFF   OFF
 * LED_STACKCREATED  1      OFF  ON    OFF
 * LED_INIRQ         2      NC   NC    ON  (momentary)
 * LED_SIGNAL        2      NC   NC    ON  (momentary)
 * LED_ASSERTION     3      ON   NC    NC  (momentary)
 * LED_PANIC         4      ON   OFF   OFF (flashing 2Hz)
