Characteristics of the I2Cbus
The I2Cbus is meant for 2way, 2line communication
between different ICs or modules. The two lines are the
serial data line (SDA) and the serial clock line (SCL). Both
lines must be connected to a positive supply via a pullup
resistor when connected to the output stages of a device.
Data transfer may only be initiated 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. Changes in the data line during the
HIGH period of the clock pulse will be interpreted as control
signals (see Figure 14).

START and STOP conditions
Both data and clock lines remain HIGH when the bus is
not busy. A START condition (S) occurs when there is a
HIGHtoLOW transition of the data line while the clock is
HIGH. A STOP condition (P) occurs when there is a
LOWtoHIGH transition of the data line while the clock is
HIGH (see Figure 15).
