13.2 PCI AC Electrical Specifications
This section describes the general AC timing parameters of the PCI bus of the MPC8349EA. Note that the
PCI_CLK or PCI_SYNC_IN signal is used as the PCI input clock depending on whether the device is
configured as a host or agent device. Table 45 provides the PCI AC timing specifications at 66 MHz.
