Operating Conditions
This table lists recommended operational voltage conditions.
This SoC contains circuitry protecting against damage due to high static voltage or electrical fields;
however, it is advised that normal precautions be taken to avoid application of any voltages higher than
maximum-rated voltages to this high-impedance circuit. Reliability of operation is enhanced if unused
inputs are tied to an appropriate logic voltage level (either GND or VCC).
This figure shows the undershoot and overshoot voltage of the 60x bus memory interface of the SoC. Note
that in PCI mode the I/O interface is different.

1 Caution: These are the recommended and tested operating conditions. Proper operation outside of these conditions
is not guaranteed.
