Data Validity
The data on the SDA line must be stable during the High period of the clock. The High or
Low state of the data line can only change when the clock signal on the SCL line is Low as
displayed in
START and STOP Conditions
Within the I
STOP conditions. See
High indicates a START condition. A Low-to-High transition on the SDA line while SCL
is High defines a STOP condition.
START and STOP conditions are always generated by the master. The bus is considered to
be busy after the START condition. The bus is considered to be free a defined time after
the STOP condition.
