19.6.3 Transfer direction specification
In addition to the 7-bit address data, the master device sends 1 bit of data that specifies the transfer direction.
When this transfer direction specification bit has a value of 0, it indicates that the master device is transmitting data to a
slave device. When the transfer direction specification bit has a value of 1, it indicates that the master device is receiving
data from a slave device.
