debug functionality (where NC means "No Change").
During the boot phases. LED1 and LED2 will show boot status. - The LED is not illuminated until the LPCXpresso completes initialization.

After the system is booted, this logic will no longer use LEDs 1 and 2. They The normal state, after initialization will be a dull glow. The brightness of

busy handling device interrupts and increase in brightness as the system becomes
idle.

The heartbeat LED is illuminated during all interrupt and signal procressing.
Normally, it will glow dimly to inicate that the LPC17xx is taking interrupts.
On an assertion PANIC, it will flash at 1Hz.
