Instructions M24256-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, 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 .
