7.2 I2C Interface

The I2C Interface is bi-directional 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 have built-in pull up resistor which drives

SDA and SCL to high when the bus is not busy. Data transfer can be initiated only when the bus is not busy.

7.2.1 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 because changes of SDA line at this time will be interpreted as START or

STOP. Bit transfer is illustrated as follows.

7.2.2 START and STOP Conditions

Both SDA and SCL lines remain HIGH when the bus is not busy. A HIGH-to-LOW transition of SDA, while

SCL is HIGH is defined as the START condition (S). A LOW-to-HIGH transition of SDA while SCL is HIGH is

defined as the STOP condition (P). The START and STOP conditions are illustrated as follows.
