11 PCI
This section describes the DC and AC electrical specifications for the PCI bus of the MPC8309.
11.1 PCI DC electrical characteristics
Table 30 provides the DC electrical characteristics for the PCI interface of the MPC8309.
11.2 PCI AC electrical specifications
This section describes the general AC timing parameters of the PCI bus of the MPC8309. Note that the
PCI_CLK or PCI_SYNC_IN signal is used as the PCI input clock depending on whether the MPC8309 is
configured as a host or agent device. Table 31 shows the PCI AC timing specifications at 66 MHz.
.
Table 32 shows the PCI AC timing specifications at 33 MHz.
