Read operations
Read operations are performed independently of the state of the Write Control (WC) signal.
After the successful completion of a Read operation, the device’s internal address counter is
incremented by one, to point to the next byte address.

Random Address Read (in memory array)
A dummy Write is first performed to load the address into this address counter (as shown in
Figure 11) but without sending a Stop condition. Then, the bus master sends another Start
condition, and repeats the device select code, with the Read/Write bit (RW) set to 1. The
device acknowledges this, and outputs the contents of the addressed byte. The bus master
must not acknowledge the byte, and terminates the transfer with a Stop condition.
