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 V
CC
).
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.
