7.3.12.2 Start and Stop Conditions

The device is controlled through an I2C-compatible interface. START and STOP conditions classify the beginning and end of the I2C session. A START condition is defined as the SDA signal going from HIGH to LOW while the SCL signal is HIGH. A STOP condition is defined as the SDA signal going from LOW to HIGH while the SCL signal is HIGH. The I2C controller device always generates the START and STOP conditions.

GUID-EEA51CC7-8B36-4DAD-9969-8B1FE2ECCF4E-low.gifFigure 7-5 Start and Stop Sequences

The I2C bus is considered busy after a START condition and free after a STOP condition. The I2C controller device can generate repeated START conditions during data transmission. A START and a repeated START condition are equivalent function-wise. Figure 7-6 shows the SDA and SCL signal timing for the I2C-compatible bus. For timing values, see the Specification section.
