I2C bus transmission method
Start and stop conditions
In the I2C bus, SDA must basically be kept in the constant state while SCL is “H” as shown below during data
transfer.

When data transfer is not made, both SCL and SDA are in the “H” state.
When SCL = SDA = “H”, change of SDA from “H” to “L” enables the start conditions to start access.
When SCL is “H”, change of SDA from “L” to “H” enables the stop conditions to stop access.
