4.5 Device addressing
To start communication between the bus master and the slave device, the bus master must
initiate a Start condition. Following this, the bus master sends the device select code, shown
in
Table 2 (on Serial Data (SDA), most significant bit first).
The 8
th
bit is the Read/Write bit (RW). This bit is set to 1 for Read and 0 for Write operations.
If a match occurs on the device select code, the corresponding device gives an
acknowledgment on Serial Data (SDA) during the 9
th
bit time. If the device does not match
the device select code, it deselects itself from the bus, and goes into Standby mode.
