... During reads, 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 (24LC164) will leave the data line HIGH to enable the master to generate the STOP con- dition. ...

... When set to one, a read operation is selected. When set to ‘0’ a write operation is selected. Following the start condition, the 24LC164 looks for the slave address for the device selected. Depending on the state of the R/W bit, the 24LC164 will select a read or write operation. Operation Control Code ...

... Then the master issues the control byte again but with the R/W bit set to a ‘1’. The 24LC164 will then issue an acknowledge and transmits the 8-bit data word. The master will not acknowledge the transfer but does generate a stop condition and the 24LC164 dis- continues transmission (Figure 7-2) ...
