Read operations
Read operations are performed independently of the state of the Write Control (WC) signal.
The device has an internal address counter which is incremented each time a byte is read.
Random Address Read
A dummy Write is first performed to load the address into this address counter (as shown in

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.
