PCI Bus Interface
As a target, the PCI controller terminates a transaction with a target disconnect due to the following:
As a target, the PCI controller responds to a transaction with a retry due to the following:
Target-abort is indicated by asserting PCI_STOP and negating PCI_DEVSEL. This indicates that the
target requires termination of the transaction and does not want the transaction retried. If a transaction is
terminated by target-abort, the received target-abort bit (bit 12) of the initiator’s bus status register and the
signaled target-abort bit (bit 11) of the target’s bus status register are set. Note that any data transferred in
a target-aborted transaction may be corrupt.
For PCI writes to local memory, if an address parity error or data parity error occurs, the PCI controller
aborts the transaction internally, but continues the transaction on the PCI bus.

It is unable to respond within eight PCI clock cycles (not including the first data phase).
The transaction is attempting to cross a 4-Kbyte boundary.
A single beat of data has been transferred and the inbound ATMU is marked non-prefetchable.
The end of a cache line has been transferred for a cache-wrap mode write transaction. See
