9.1.2.2 Synchronous Negotiation Started by the Target
If the file recognizes that negotiation is required, the file sends a S D R message to the initiator with minimum
transfer period on the current receiver mode. The file interprets the Initiator corresponding transfer period as
shown in the following figure Figure 129 on page 166:
