Start condition. The master device drives SDA from high to low while SCL is high.
Slave address
Indicates the direction of data transfer; from the slave device to the master device when
R/W is 1, or from the master device to the slave device when R/W is 0.
Acknowledge. The receive device drives SDA low.
Stop condition. The master device drives SDA from low to high while SCL is high.
