Write operations
Following a Start condition the bus master sends a device select code with the Read/Write
bit (RW) reset to 0. The device acknowledges this, as shown in
address byte. The device responds to the address byte with an acknowledge bit, and then
waits for the data byte.
When the bus master generates a Stop condition immediately after a data byte’s Ack bit (in
the “10
cycle is triggered. A Stop condition at any other time slot does not trigger the internal write
cycle.
During the internal Write cycle, Serial Data (SDA) and Serial Clock (SCL) are ignored, and
the device does not respond to any requests.
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 (during
the period from the Start condition until the end of the address byte), the device replies to
the data byte with NoAck, as shown in
