13 PCI
This section describes the DC and AC electrical specifications for the PCI bus of the MPC8347E.
13.1
Table 40
13.2
This section describes the general AC timing parameters of the PCI bus of the MPC8347E. Note that the
PCI_CLK or PCI_SYNC_IN signal is used as the PCI input clock depending on whether the MPC8347E
is configured as a host or agent device.
