PCI Arbiter
The PCI arbiter on the Lite5200B utilizes the REQ line from each PCI slot to arbitrate the return GNT from
the MPC5200B. The arbitration logic utilizes a round robin approach in order to ensure that both PCI
devices may communicate with the MPC5200B. For further information on PLD arbitration logic please
refer to the application included in this kit.
