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 24LCS22A.
The eighth bit of slave address determines whether the
master device wants to read or write to the 24LCS22A
(Figure 3-7).
The 24LCS22A 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.
