10 / 88 page  MPC8313E PowerQUICC™ II Pro Processor Hardware Specifications, Rev. 0 10 Freescale Semiconductor Electrical Characteristics Figure 3 shows the undershoot and overshoot voltage of the PCI interface of the MPC8313E for the 3.3-V signals, respectively. Figure 3. Maximum AC Waveforms on PCI Interface for 3.3-V Signaling 2.1.3 Output Driver Characteristics Table 3 provides information on the characteristics of the output driver strengths. The values are preliminary estimates. 2.2 Power Sequencing The MPC8313E does not require the core supply voltage and IO supply voltages to be applied in any particular order. Note that during the power ramp-up, before the power supplies are stable, there might be a period when IO pins are actively driven. After the power is stable, as long as PORESET is asserted, most IO pins are tri-stated. In order to minimize the time that IO pins are being actively driven, it is Table 3.
