8. Characteristics of the I 2 C-bus
The I 2 C-bus is for bidirectional, 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 when connected to the output
stages of a device. Data transfer may be initiated only when the bus is not busy.
8.1 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 (see Figure 13 ).

8.2 START and STOP conditions
Both data and clock lines remain HIGH when the 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 (see Figure 14 ).

8.3 System configuration
A device generating a message is a transmitter, a device receiving a message is the
receiver. The device that controls the message is the master and the devices which are
controlled by the master are the slaves (see Figure 15 ).
