Instructions

5.1.1

Byte Write

After the device select code and the address byte, 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. 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 6.

Figure 6. Write mode sequences with WC = 0 (data write enabled)
