the SDA line to be stable during the entire high period of the clock pulse (see Figure 42). All devices recognize
the address sent by the master and compare it to their internal fixed addresses. Only the slave device with a
matching address generates an acknowledge (see Figure 43) by pulling the SDA line low during the entire high
period of the ninth SCL cycle. Upon detecting this acknowledge, the master knows that communication link with a
slave has been established.
Figure 42. Bit Transfer on the Serial Interface
The master generates further SCL cycles to either transmit data to the slave (R/W bit 1) or receive data from the
slave (R/W bit 0). In either case, the receiver needs to acknowledge the data sent by the transmitter. So an
acknowledge signal can either be generated by the master or by the slave, depending on which one is the
receiver. 9-bit valid data sequences consisting of 8-bit data and 1-bit acknowledge can continue as long as
necessary.
To signal the end of the data transfer, the master generates a stop condition by pulling the SDA line from low to
high while the SCL line is high (see Figure 41). This releases the bus and stops the communication link with the
addressed slave. All I2C compatible devices must recognize the stop condition. Upon the receipt of a stop
condition, all devices know that the bus is released, and they wait for a start condition followed by a matching
address.
Attempting to read data from register addresses not listed in this section will result in 00h being read out.
