Operation
I
Start condition. The master device drives SDA from high to low while SCL is high.
Slave address, by which the master device selects a slave device.
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.
