* RedLED PTD16 (FTM0 CH1)

* GreenLED PTB13 (FTM0 CH1)
|
|
* BlueLED PTD15 (FTM0 CH0)

|
|
* SYMBOL Meaning LED state

* 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)
