Slave Address: After the master initiates a start condition, it must output the address of the device to be

accessed. The most significant four bits of the slave address are called the “device identifier.” The identifier

for the 24LLC16 is “1010B”. The next three bits (B2, B1, B0) are for block selection. They are used by the

master to select which of the blocks of internal memory (1 block=256 words) are to be accessed. (see Table
