The master device changes the SDA signal from high to low while the SCL signal is held high.
Data is transmitted when:
R/W value is 1: From the slave device to the master device
R/W value is 0: From the master device to the slave device
The receive device sets the SDA signal to low.
The master device changes the SDA signal from low to high while the SCL signal is held high.
