This section describes the DC and AC electrical specifications for the PCI bus of the MPC8349E.
13.1
PCI DC Electrical Characteristics
Table 40 provides the DC electrical characteristics for the PCI interface of the MPC8349E.
13.2
PCI AC Electrical Specifications
This section describes the general AC timing parameters of the PCI bus of the MPC8349E. Note that the
PCI_CLK or PCI_SYNC_IN signal is used as the PCI input clock depending on whether the MPC8349E
is configured as a host or agent device. Table 41 provides the PCI AC timing specifications at 66 MHz.
