"WebbNote: The above waveform is slightly exaggerated. You will not notice SDA going high in (2) and (5). A small spike might barely be visible. Note: An Acknowledge of a byte received from a slave is always necessary, EXCEPT on the last byte received. If the master wants to stop receiving data from the slave, it must be able to send a stop condition. " - I2c ack waveform
