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. Data
transfer may be initiated only when the bus is not busy.
8.1
Bit transfer
(see Fig.12)
of the clock pulse as changes in the data line at this time will be interpreted as a control signal.
8.2
Start and stop conditions
(see Fig.13)
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).
