CHARACTERISTICS OF THE I2C-BUS
The I2C-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 6).
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 7).
System configuration
A device generating a message is a transmitter: a device receiving
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 8).

NOTES:
1. Cb = total capacitance of one bus line in pF.
2. tVD;ACK = time for Acknowledgement signal from SCL LOW to SDA (out) LOW.
3. tVD;DAT = minimum time for SDA data out to be valid following SCL LOW.
