characteristics of the PORESET signal, which can be used as PCI RST in applications where the device is
a PCI agent, deviates from the standard PCI levels.
14.2
This section describes the general AC timing parameters of the PCI bus of the device. Note that the
PCI_CLK/PCI_SYNC_IN or CLKIN signal is used as the PCI input clock depending on whether the
MPC8378E is configured as a host or agent device. CLKIN is used when the device is in host mode.
