Figure 33 shows the internal distribution of clocks within the MPC8343E.
Figure 33. MPC8343E Clock Subsystem
The primary clock source for the MPC8343E can be one of two inputs, CLKIN or PCI_CLK, depending
on whether the device is configured in PCI host or PCI agent mode. When the MPC8343E is configured
as a PCI host device, CLKIN is its primary input clock. CLKIN feeds the PCI clock divider (
÷2) and the
multiplexors for PCI_SYNC_OUT and PCI_CLK_OUT. The CFG_CLKIN_DIV configuration input
selects whether CLKIN or CLKIN/2 is driven out on the PCI_SYNC_OUT signal. The OCCR[PCICDn]
parameters select whether CLKIN or CLKIN/2 is driven out on the PCI_CLK_OUTn signals.
PCI_SYNC_OUT is connected externally to PCI_SYNC_IN to allow the internal clock subsystem to
synchronize to the system PCI clocks. PCI_SYNC_OUT must be connected properly to PCI_SYNC_IN,
with equal delay to all PCI agent devices in the system, to allow the MPC8343E to function. When the
MPC8343E is configured as a PCI agent device, PCI_CLK is the primary input clock. When the
MPC8343E is configured as a PCI agent device the CLKIN signal should be tied to GND.
