14 PCI

This section describes the DC and AC electrical specifications for the PCI bus of the MPC8314E.

14.1

PCI DC Electrical Characteristics

This table provides the DC electrical characteristics for the PCI interface.

14.2

PCI AC Electrical Specifications

This section describes the general AC timing parameters of the PCI bus. Note that the PCI_CLK or

PCI_SYNC_IN signal is used as the PCI input clock depending on whether the MPC8314E is configured

as a host or agent device. This table shows the PCI AC timing specifications at 66 MHz.
