6.1.1

Byte write

After the device select code and the address bytes, the bus master sends one data byte. If the addressed location

is write-protected, with the SWP bit set to '1', the device replies with NoACK, and the location is not modified, as

shown in 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.
