Transmitter must release the SDA line at this point
allowing the Receiver to pull the SDA line low to
acknowledge the previous eight bits of data.
Receiver must release the SDA line at this point
so the Transmitter can continue sending data.

Device Addressing
After generating a START condition, the bus master
transmits a control byte consisting of a slave address
and a Read/Write bit that indicates what type of opera-
tion is to be performed. The slave address consists of
a 4-bit device code (1010) followed by three don’t care
bits.
The last bit of the control byte determines the operation
to be performed. When set to a one a read operation is
selected, and when set to a zero a write operation is
selected. (Figure 7-5). The bus is monitored for its cor-
responding slave address all the time. It generates an
acknowledge bit if the slave address was true and it is
not in a programming mode.
