Write operations
Following a Start condition the bus master sends a device select code with the R/W bit (RW)
reset to 0. The device acknowledges this, as shown in
bytes. The device responds to each address byte with an acknowledge bit, and then waits
for the data byte.

After the Stop condition and the successful completion of an internal Write cycle (t
device internal address counter is automatically incremented to point to the next byte after
the last modified byte.
During the internal Write cycle, Serial Data (SDA) is disabled internally, and the device does
not respond to any requests.
If the Write Control input (WC) is driven High, the Write instruction is not executed and the
accompanying data bytes are not acknowledged, as shown in
