CHARACTERISTICS OF THE I

C-BUS
The I
2
C-bus is for 2-way, 2-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.
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 control signals (see Figure 5).

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 6).
System configuration
A device generating a message is a
transmitter
, a device receiving is the
receiver
. The device initiates a transfer is the
master
and the
devices which are controlled by the master are the
slaves
(see Figure 7).
