NO OPERATION
The NO OPERATION message is sent from an initiator in response to a target's request for a message when
the initiator does not currently have any other valid message to send.
For example, if the target does not respond to the attention condition until a later phase and at that time the
original message is no longer valid the initiator may send the NO OPERATION message when the target
switches to a MESSAGE OUT phase.
