Clock Input Timing
This section provides the clock input DC and AC electrical characteristics for the MPC8379E. Note that
the PCI_CLK/PCI_SYNC_IN signal or CLKIN signal is used as the PCI input clock depending on
whether the device is configured as a host or agent device. CLKIN is used when the device is in host mode.
