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 processor
transmits a control byte consisting of a EEPROM
address and a Read/Write bit that indicates what type
of operation is to be performed. The EEPROM 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 6-4). The bus is monitored for its cor-
responding EEPROM address all the time. It generates
an acknowledge bit if the EEPROM address was true
and it is not in a programming mode.
