/* LEDs: There are three LEDs on board the SAML21 Xplained Pro board: The EDBG
* controls two of the LEDs, a power LED and a status LED. There is only
* one user controllable LED, a yellow LED labelled STATIS near the SAML21 USB
* connector.
*
* This LED is controlled by PB10 and the LED can be activated by driving PB10
* to GND.
*
* When CONFIG_ARCH_LEDS is defined in the NuttX configuration, NuttX will
* control the LED as follows:
*
* SYMBOL Meaning LED
* ------------------- ----------------------- ------
* LED_STARTED NuttX has been started OFF
* LED_HEAPALLOCATE Heap has been allocated OFF
* LED_IRQSENABLED Interrupts enabled OFF
* LED_STACKCREATED Idle stack created ON
* LED_INIRQ In an interrupt N/C
* LED_SIGNAL In a signal handler N/C
* LED_ASSERTION An assertion failed N/C
* LED_PANIC The system has crashed FLASH
*
* Thus if the LED is statically on, NuttX has successfully booted and is,
* apparently, running normally. If the LED is flashing at approximately
* 2Hz, then a fatal error has been detected and the system has halted.
