9.1 CHARACTERISTICS OF THE I

C SERIAL INTERFACE
The I
2
C interface is for bi-directional, two-line communication between different ICs or modules. The two
lines are a serial data line (SDA) and a serial clock line (SCL). Both lines must be connected to a positive
supply via a pull-up resistor. Data transfer may be initiated only when the interface bus is not busy.
9.1.1 Bit transfer
One data bit is transferred during each clock pulse. The data on the SDA line must remain stable during
the HIGH period of the clock pulse, as changes in the data line at this time will be interpreted as a control
signal.

9.1.2 Start and stop conditions
Both data and clock lines remain HIGH when the interface bus is not busy. A HIGH-to-LOW transition of
the data line while the clock is HIGH is defined as the start condition (S). A LOW-to-HIGH transition of the
data line while the clock is HIGH is defined as the stop condition (P).
