Instructions M24C08-DRE
After the device select code and the address bytes, the bus master sends one data byte. If the addressed location is Write-protected, by Write Control (WC) being driven high, the device replies with NoAck on the received data byte, and the location is not modified (see
Figure 6 ). If, instead, the addressed location is not Write-protected, the device replies with
Ack. The bus master terminates the transfer by generating a Stop condition, as shown in
Figure 5 .
Figure 5. Write mode sequences with WC = 0 (data write enabled)
