BYTE WRITE OPERATION

In a complete byte write operation, the master transmits the slave address, word address, and one data byte to

the 24LLC16 slave device (see Figure 5-9).

set to “0” onto the bus. Then the addressed 24LLC16 generates an ACK, and waits for the next byte. The next

byte to be transmitted by the master is the word address. This 8-bit address is written into the word address

pointer of the 24LLC16

When the 24LLC16 receives the word address, it responds by issuing an ACK and then waits for the next 8-

bit data. When it receives the data byte, the 24LLC16 again responds with an ACK. The master terminates

the transfer by generating a Stop condition, at which time the 24LLC16 begins the internal write cycle.

While the internal write cycle is in progress, all 24LLC16 inputs are disabled and the 24LLC16 does not

respond to any additional request from the master.
