Byte Write. STMicroelectronics M24C02-DRE

Instructions M24C02-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 .
