/* The NuTiny has a single green LED that can be controlled from sofware.
* This LED is connected to PIN17. It is pulled high so a low value will
* illuminate the LED.
*
* If CONFIG_ARCH_LEDs is defined, then NuttX will control the LED on board the
* NuTiny. The following definitions describe how NuttX controls the LEDs:
*
* SYMBOL Meaning LED state
* Initially all LED is OFF
* ------------------- ----------------------- ------------- ------------
* LED_STARTED NuttX has been started LED ON
* LED_HEAPALLOCATE Heap has been allocated LED ON
* LED_IRQSENABLED Interrupts enabled LED ON
* LED_STACKCREATED Idle stack created LED ON
* LED_INIRQ In an interrupt LED should glow
* LED_SIGNAL In a signal handler LED might glow
* LED_ASSERTION An assertion failed LED ON while handling the assertion
* LED_PANIC The system has crashed LED Blinking at 2Hz
* LED_IDLE NUC1XX is is sleep mode (Optional, not used)
