3. Data Transmission
Changing the SDA line while the SCL line is low, data is transmitted.
Changing the SDA line while the SCL line is high, a start or stop condition is recognized.

4. Acknowledge
The unit of data transmission is 8 bits. During the 9th clock cycle period the receiver on the bus pulls down
the SDA line to acknowledge the receipt of the 8-bit data.
When a internal write cycle is in progress, the device does not generate an acknowledge.
