C-bus/SPI interface, 64-byte FIFOs, IrDA SIR
Another way for a master to communicate with several different devices would be by using
a ‘repeated START’. After the last byte of the transaction was transferred, including its
acknowledge (or negative acknowledge), the master issues another START, followed by
address byte and data—without effecting a STOP. The master may communicate with a
number of different devices, combining ‘reads’ and ‘writes’. After the last transfer takes
place, the master issues a STOP and releases the bus. Possible data formats are
demonstrated in
Figure 17
. Note that the repeated START allows for both change of a
slave and a change of direction, without releasing the bus. We shall see later on that the
change of direction feature can come in handy even when dealing with a single device.
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 it occupies the bus for a long time and thus preventing
other devices from initiating transfers.
