17.4.2.8
A PCI transaction may be terminated by either the initiator or the target. The initiator is ultimately
responsible for concluding all transactions, regardless of the cause of the termination. All transactions are
concluded when PCI_FRAME and PCI_IRDY are both negated, indicating the bus is idle.
17.4.2.8.1
Normally, a master initiates termination by negating PCI_FRAME and asserting PCI_IRDY. This
indicates to the target that the final data phase is in progress. The final data transfer occurs when both
PCI_TRDY and PCI_IRDY are asserted. The transaction is considered complete when data is transferred
