Revision A1
I
2
C PROTOCOL
Since the I
2
C protocol allows multiple devices on the bus, each device must have an address. This
address is known as a “Slave Address”. A Slave Address consists of 7 bits, followed by a single bit that
indicates the direction of data flow. This single bit is 1 for a Write cycle, which indicates the data is
being sent from the current bus master to the device being addressed. This single bit is a 0 for a Read
cycle, which indicates that the data is being sent from the device being addressed to the current bus
master.
Before any data is transmitted on the I
2
C interface, the current bus master must address the slave it
wishes to transfer data to or from. The Slave Address is always sent out as the 1
byte following the
Start Condition sequence. An example of a Master transmitting an address to a ISD5216 slave is
shown below. In this case, the Master is writing data to the slave and the R/W bit is “0”, i.e. a Write
cycle. All the bits transferred are from the Master to the Slave, except for the indicated Acknowledge
bits.

A common procedure in the ISD5116 is the reading of the Status Bytes. The Read Status condition in
the ISD5216 is triggered when the Master addresses the chip with its proper Slave Address,
immediately followed by the R/W bit set to a “0” and without the Command Byte being sent. This is an
example of the Master sending to the Slave, immediately followed by the Slave sending data back to
the Master. The “N” not-acknowledge cycle from the Master ends the transfer of data from the Slave.
