Table 3.
For the bus master to communicate to the slave device, the bus master must initiate a Start
condition and followed by the slave device address. Accompanying the slave device
address, there is a Read/Write bit (R/W). The bit is set to 1 for Read and 0 for write
operation.
If a match occurs on the slave device address, the corresponding device gives an
acknowledge on the SDA during the 9th bit time. If there is no match, it deselects itself from
the bus by not responding to the transaction.
