Data validity
As shown by
the clock. The HIGH and LOW state of the data line can only change when the clock signal
on the SCL line is LOW.
Start and stop conditions
As shown by
SCL is HIGH. The stop condition is a LOW to HIGH transition of the SDA line while SCL is
HIGH.
Byte format
Every byte transferred to the SDA line must contain 8 bits. Each byte must be followed by an
acknowledge bit. The MSB is transferred first.
