... 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 (24LC174) 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 zero a write operation is selected. Following the start condition, the 24LC174 looks for the slave address for the device selected. Depending on the state of the R/W bit, the 24LC174 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 one. The 24LC174 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 24LC174 dis- continues transmission (Figure 8-2) ...

... If tied WRITE operations are inhibited. The CC entire memory will be write-protected. Read operations are not affected. This feature allows the user to use the 24LC174 as a serial ROM when WP is enabled (tied to Vcc). 8.4 A0, A1, A2 These pins are used to configure the proper chip address in multiple-chip applications (more than one 24LC174 on the same bus) ...
