way that the SDA line is stable low during the high

course, setup and hold times must be taken into
account. A master must signal an end of data to the

slave by not generating an Acknowledge bit on the last
byte that has been clocked out of the slave. In this
case, the slave must leave the data line high to enable
the master to generate the Stop condition (Figure 4-2).

Data from transmitter
Transmitter must release the SDA line at this point
allowing the Receiver to pull the SDA line low to
acknowledge the previous eight bits of data.
Data from transmitter
Receiver must release the SDA line at this point
so the Transmitter can continue sending data.
