In a single master system, the ‘Repeated START’ mechanism may be more efficient than
terminating each transfer with a STOP and starting again. In a multimaster environment,
the determination of which format is more efficient could be more complicated, as when a
master is using repeated STARTs occupies the bus for a long time, and thus preventing
other devices from initiating transfers.
