/* The S32K148EVB has one RGB LED:
 *
 *   RedLED   PTE21
 *   GreenLED PTE22
 *   BlueLED  PTE23
 *
 * An output of '1' illuminates the LED.
 *
 * If CONFIG_ARCH_LEDs is defined, then NuttX will control the LED on board
 * the Freedom K66F.  The following definitions describe how NuttX controls
 * the LEDs:
 *
 *   SYMBOL                Meaning                 LED state
 *                                                 RED   GREEN  BLUE
 *   -------------------  -----------------------  -----------------
 *   LED_STARTED          NuttX has been started    OFF  OFF  OFF
 *   LED_HEAPALLOCATE     Heap has been allocated   OFF  OFF  ON
 *   LED_IRQSENABLED      Interrupts enabled        OFF  OFF  ON
 *   LED_STACKCREATED     Idle stack created        OFF  ON   OFF
 *   LED_INIRQ            In an interrupt          (no change)
 *   LED_SIGNAL           In a signal handler      (no change)
 *   LED_ASSERTION        An assertion failed      (no change)
 *   LED_PANIC            The system has crashed    FLASH OFF OFF
 *   LED_IDLE             K66 is in sleep mode     (Optional, not used)
