The PCI interface on the MPC5200B is designed to PCI Version 2.2 and supports 33 MHz and 66 MHz PCI operations. See the
PCI Local Bus Specification; the component section specifies the electrical and timing parameters for PCI components with the
intent that components connect directly together whether on the planar or an expansion board, without any external buffers or
other “glue logic.” Parameters apply at the package pins, not at expansion board edge connectors.
The MPC5200B is always the source of the PCI CLK. The clock waveform must be delivered to each 33 MHz or 66 MHz PCI
component in the system.
