Note:
1. In asynchronous PCI mode the minimum PCIClk frequency is 1/8 the PLB Clock. Refer to the
PowerPC 405GPr Embedded Proces-
sor User’s Manual for more information.
2. In synchronous PCI mode the PCI clock is derived from SysClk and the PCIClk input pin is unused.
3. TOPB is the period in ns of the OPB clock. The maximum OPB clock frequency is 50 MHz for 200MHz parts and 66.66MHz for
266 MHz parts.
