... Device Addressing A control byte is the first byte received following the Start condition from the master device (Figure 3-2). The control byte consists of a four-bit control code. For the 24XX32A, this is set as ‘1010’ binary for read and write operations. The next three bits of the control byte are the Chip Select bits (A2, A1, A0) ...
