Freescale Semiconductor
Operating Conditions
This device 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).
Figure 2 shows the undershoot and overshoot voltage of the 60x bus memory interface of the MPC8272.
Note that in PCI mode the I/O interface is different.
