/* LEDs: There are three LEDs on board the SAM4L 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 labeled LED0 near
* the SAM4L USB connector.
*
* This LED is controlled by PC07 and LED0 can be activated by driving the
* PC07 to GND.
*
* When CONFIG_ARCH_LEDS is defined in the NuttX configuration, NuttX will
* control LED0 as follows:
*
* SYMBOL Meaning LED0
* ------------------- ----------------------- ------
* 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 is LED0 is statically on, NuttX has successfully booted and is,
* apparently, running normmally. If LED0 is flashing at approximately
* 2Hz, then a fatal error has been detected and the system has halted.

*
* The SAM4L Xplained Pro contains two mechanical buttons.
* One button is the RESET button connected to the SAM4L reset line and the
* other is a generic user configurable button.
