The three disconnect terminations are unique in the data transferred at the end of the transaction. For
disconnect A, the initiator is negating PCI_IRDY when the target asserts PCI_STOP and data is transferred
only at the end of the current data phase. For disconnect B, the target negates PCI_TRDY one clock after
