BCM54612E have 4 multi-functional LED pins that can be configured through register setting; the LED4 pin can be configured to a 125MHz reference clock output by setting the spare register. Since the dedicated CLK125 reference clock pin is not brought out on the 48-Pin MLP, the LED4 pin is the only pin to provide such function in this package, and therefore it is beneficial to just enable the reference clock by default.
