Datasheet

The processor uses seven voltage identification pins,VID[6:0], to support automatic 

selection of power supply voltages. The VID pins for the processor are CMOS outputs 

driven by the processor VID circuitry. 

 specifies the voltage level corresponding 

to the state of VID[6:0]. A 1 in the table refers to a high-voltage level and a 0 refers to 

a low-voltage level.
