... Device Addressing A control byte is the first byte received following the Start condition from the master device. The control byte consists of a four-bit control code, for the 24XX65 this is set as ‘1010’ binary for read and write operations. The next three bits of the control byte are the device select bits (A2, A1, A0) ...

... Security Options The 24XX65 has a sophisticated mechanism for write protecting portions of the array. This write-protect function is programmable and allows the user to protect 0-15 contiguous 4K blocks. The user sets the security option by sending to the device the starting block number for the protected region and the number of blocks to be protected ...
