Figure 3. Data Transfer on I2C Serial Bus
Depending upon the state of the R/
W bit, two types of data transfer are possible:
1.
Data transfer from a master transmitter to a slave receiver. The first byte transmitted by the master is the
slave address. Next follows a number of data bytes. The slave returns an acknowledge bit after each received
byte. Data is transferred with the most significant bit (MSB) first.
2.
Data transfer from a slave transmitter to a master receiver. The first byte (the slave address) is transmitted
by the master. The slave then returns an acknowledge bit. This is followed by the slave transmitting a number
of data bytes. The master returns an acknowledge bit after all received bytes other than the last byte. At the
end of the last received byte, a “not acknowledge” is returned.
The master device generates all the serial clock pulses and the START and STOP conditions. A transfer is
ended with a STOP condition or with a repeated START condition. Since a repeated START condition is also
the beginning of the next serial transfer, the bus will not be released. Data is transferred with the most
significant bit (MSB) first.
