+1.8V supply to the internal clock multiplier. This pin  
requires a 100nF decouplingcapacitor.

* 48 pin LQFP package only This power input is internally  
connected to VREG_OUT.

All other packages need this pin connectedto a 1.8V power  
source. Most common applications will connect this to  
VREG_OUT.
