PCI arbiter doubt

Hi all,

I have some basic doubts on PCI arbiter.

1)how is the framen controlled -- i guess it is a shared resource on the PCI bus wher all the devices sitting on the PCI bus have access to it. 2)If a request is received from a device on PCI bus ,should the grant be issued immediately or should the PCI arbiter wait until the framen is dropped (asserted). 3)If a request is received from a device on PCI bus , but the framen is not dropped at all.how should the PCI arbiter react to this condition.

Regards, Praveen
