3.1.6 SLAVE ADDRESS

After generating a Start condition, the bus master

transmits the slave address consisting of a 7-bit device

code ‘1010000’ for the 24LCS21.

The eighth bit of the slave address determines whether

the master device wants to read or write to the

24LCS21 (Figure 3-5).

The 24LCS21 monitors the bus for its corresponding

slave address continuously. It generates an

Acknowledge bit if the slave address was true and it is

not in a programming mode.
