SDA Signal
SCL Signal
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
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 at a defined time after
the STOP condition.
Every character transferred on the SDA line must be a single 8-bit byte. The number of
bytes that can be transmitted per transfer is unrestricted. Each byte must be followed by an
