of reordering allowed. Retry is not considered an error condition, so there is no error logging 
or reporting done on a retry.

•

The 41210 terminates a transaction with retry to an initiator when one of the following 
conditions is met:

— The 41210 receives a new memory read transaction, and the 41210 delayed transaction 

queue is full.

— The 41210 receives a memory read that has already been queued, but has not completed 

on PCI Express*.

— The 41210 receives a memory read that has been queued and completed on PCI Express*, 

but ordering rules require a downstream posted write to complete ahead of it.

— A LOCK transaction has been established from PCI Express*-to-PCI.

— The 41210 receives a memory write transaction, and the 41210 has no free buffer space to 

accept the write.

— A memory write transaction is from a master other than the master that was previously 

retried (starvation prevention mechanism).

•

The 41210 disconnects an initiator when one of the following conditions is met:

— The 41210 cannot accept any more write data.

— The 41210 has no more read data to deliver.

— The memory address is non-linear.

— The inverse decode window ends.

•

The 41210 returns a target abort to PCI when the following condition is met.

— The cycle master aborted, or the target aborted on PCI Express*/peer PCI.
