1.9 GLOBAL OUTPUT ENABLE AND LOCK DETECT
The GOE pin provides an internal pull-up resistor. If it is un-
terminated externally, the clock output states are determined
by the Clock Output Enable bits (CLKoutX_EN) and the
EN_CLKout_Global bit.

By programming the PLL_MUX register to Digital Lock Detect
Active High (See 2.5.2), the Lock Detect (LD) pin can be con-
nected to the GOE pin in which case all outputs are set low
automatically if the synthesizer is not locked.
