*
* ------------- --------
* RGB LED KL25Z128
* ------------- --------
* Red Cathode PTB18
* Green Cathode PTB19
* Blue Cathode PTD1
*
* NOTE: PTD1 is also connected to the I/O header on J2 pin 10 (also known as D13).
*
* If CONFIG_ARCH_LEDs is defined, then NuttX will control the LED on board the

*
* SYMBOL Meaning LED state
* Initially all LED is OFF
* ------------------- ----------------------- --------------------------
* LED_STARTED NuttX has been started
* LED_HEAPALLOCATE Heap has been allocated
* LED_IRQSENABLED Interrupts enabled
* LED_STACKCREATED Idle stack created
* LED_INIRQ In an interrupt
* LED_SIGNAL In a signal handler
* LED_ASSERTION An assertion failed
* LED_PANIC The system has crashed
* LED_IDLE K25Z1XX is in sleep mode (Optional, not used)
