Note: The LOSxB LEDs may be dim when the EVB is first plugged in. Once
ClockBuilderPro is launched, the LEDs will begin to function normally.
D5, D7, D14, D15, D16, and D17 are status LEDs indicating the device alarms currently asserted. D11 is
illuminated when USB +5 V supply voltage is present. D12 and D13 are status LEDs showing on-board MCU
activity.
