The first byte of a Write Byte access is the command code. The next one byte is the data to be written. In this
example the master asserts GL9711
’
s address followed by the write bit. GL9711 acknowledges and the master
delivers the command code. GL9711 again acknowledges before the master sends the data byte. GL9711
acknowledges the data byte, and the entire transaction is finished with a STOP condition.

Write Byte Protocol
Reading data is slightly more complicated than writing data. First the host must write a command to GL9711.
Then it must follow that command with a repeated START condition to denote a read from GL9711
’
s address.
GL9711 then returns one byte of data.
Note that there is no STOP condition before the repeated START condition, and that a NACK signified the end
of the read transfer.

Read Byte Protocol
GL9711 requires a minimum time (16us) to reach the steady state after power on. So the master must start
programming at least 16us later after power on.
