Power and Signal Distribution

7.3.2 Low Voltage Production/Distribution

Auxiliary voltages less than 5 volts and all voltages less than 3.3 volts are produced through
regulator circuitry (Figure 7-6) on the system board.
Figure 7-6. Low Voltage Supply and Distribution Diagram
The VccP regulator produces the VccP (processor core) voltage according to the strapping of
signals VID0..5 by the processor and may range from 0.8375 to 1.6 VDC.
