ABSTRACT:
When a device on a computer communications bus receives a request to enter into a transaction and is not yet ready to perform the transaction, it sends a retry signal to the requesting device to indicate to it that it should terminate the transaction that it has initiated. If the responding device may later be ready to engage in the transaction if the transaction is initiated again some time in the future, the signal is a retry signal and differs from the signal that the requesting device would receive if the transaction were to be terminated for some other reason. As a result, the master device can be arranged to re-initiate only those transactions for which there is a likelihood that they can be carried out to completion when they are attempted again.
