3.3 Voltage Identification and Power Sequencing
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. Tab l e 2 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.
