When Not Using the Internal Power Supply Step-Down Circuit  
When the internal power supply step-down circuit is not used, connect the external power supply  
to the VCC pin and CVCC pin, as shown in figure 14-2. The external power supply is then input  
directly to the internal power supply.  
Note: The permissible range for the power supply voltage is 1.8 V to 5.5 V. Operation cannot be  
guaranteed if a voltage outside this range (less than 1.8 V or more than 5.5 V) is input.
