14 PCI
This section describes the DC and AC electrical specifications for the PCI bus of the MPC8315E.
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 MPC8315E is configured
as a host or agent device. This table shows the PCI AC timing specifications at 66 MHz.
