Data transmission is completed by either the reception of a stop condition or the reception of the data word sent
to the device. A stop condition is recognized as a low to high transition of the SDA input during the high portion
of the SCL signal. All other transitions of the SDA line must occur during the low portion of the SCL signal. An
acknowledge is issued after the reception of valid address, sub-address and data words. Reference Figure 14.
