To achieve good performance, the  
negative supply terminals should be  
connected to low impedance ground  
plane.  
Note(s)  
(1) For the VDD_CORE supply, voltage scaling should be applied to optimize power consumption  
and CPU speed performance. For normal operation with fclk (CPU ARM-922T clock) frequencies  
below 200 MHz, CVDD (supply of VDD_CORE) can be set to a lower value of 1.10 V. Only for setting  
fclk of the CPU to clock frequencies above 200 MHz, the VDD_CORE supply voltage must be set to  
1.20 V typical conditions.
